Compression of Stonewool Insulation PDF Print E-mail
Thursday, 16 April 2015 10:51

Stonewool insulation is a mineral wool insulation product, manufactured from molten rock. It is a natural fibrous material, and has been widely recognized for decades for its thermal and sound insulating properties, as well as its excellent performance for the fire protection of lives and structures.  The use of technologically advanced machinery for the manufacture of stonewool insulation ensures stabilized production and superior quality final products.


Fibran SA, a part of the FIBRAN Group, produces stonewool insulation products with the brand name FIBRANgeo.  FIBRANgeo stonewool is produced from volcanic minerals such as basalt, limestone, dolomite, and bauxite. The minerals, as raw materials, are initially fused in an electric furnace and the vitreous melt is then spun into fibres. The maintenance of steady temperatures in the furnace enables the production of uniform stonewool fibres with excellent technical characteristics.  In addition, the levels of polluting sulfur and nitrogen oxide (SOX and NOX) gas emissions of the electric furnace are significantly lower than those of the blast method.

 

Once past the spinning phase, the loose stonewool fibres, with the addition of adhesive resin and special silicon compounds, acquire cohesiveness and hydrophobicity. Finally, FIBRANgeo stonewool Building Insulation products are formed in boards, rolls and loose fill in a variety of dimensions.  The above products may also be manufactured with facings. FIBRANgeo stonewool insulation products provide excellent thermal insulation, with a very low thermal conductivity coefficient and excellent thermal resistance even at high temperatures. The fibres’ softening temperature is over 1,000 °C and their binder starts to evaporate when its temperature exceeds 200 °C.  Therefore, FIBRANgeo stonewool insulation products are capable of withstanding high temperatures, up to 750 °C. These characteristics make FIBRANgeo products a perfect choice for thermal insulation, sound insulation and fire protection at construction projects.

 

At their headquarters in Greece, FIBRAN have added to their quality control testing lab with their recent purchase of a 10kN model 10ST tension and compression strength tester. The new machine will join their existing Tinius Olsen H10kT and model H10kS (seen here), and ensure consistent product quality.


 
Testing Extruded Polystyrene Insulation PDF Print E-mail
Wednesday, 15 April 2015 15:41

Polystyrene insulation is a type of rigid foam insulation which is commonly used in residential and commercial settings. It has an exceptional ability to insulate against noise and extreme temperatures, it is waterproof, and it has withstood the test of time. These qualities combine to make polystyrene insulation an exceptionally useful product.

As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behavior is exploited for extrusion, and also for molding and vacuum forming, since it can be cast into molds with fine detail. Polystyrene (abbreviated to PS) is used for producing disposable plastic cutlery and dinnerware, CD "jewel" cases, smoke detector housings, license plate frames, plastic model assembly kits, and many other objects where a rigid, economical plastic is desired. Production methods for these products include thermoforming (vacuum forming) and injection molding.

Extruded polystyrene is suitable for a wide variety of applications, both in building construction and in industry, but primarily as thermal insulation due to its exceptional technical characteristics. Polystyrene from Fibran SA is produced with the use of environmentally friendly gases, and in accordance with the European requirements for sustainable materials and can be seen in their signature turquoise colour. Fibran uses extruded polystyrene to create a complete energy shield that protects against extreme temperatures and maintains its physical and chemical characteristics even after having been exposed to long-term loads and environments with increased humidity levels. FIBRANxps thermal insulation is supplied in boards as well as in composite prefabricated elements, combined with plain or water-resistant gypsum boards, white cement mortar and ceramic tiles.

To ensure continuing product quality, Fibran uses a 10kN Tinius Olsen dual column bench top machines to test the tensile strength, shear strength and compressive strength of their extruded polystyrene products and has recently increased their testing capabilities with the addition of a new model 10ST.

3D Printed Products Testing PDF Print E-mail
Friday, 27 February 2015 08:41

3D printing has evolved from science fiction to science fact and promises to be an exciting and rapidly expanding market. 3D printing enables engineers to check the fit of different parts long before they commit to costly production; architects to show detailed and relatively low-cost scale models to their clients; and, perhaps most exciting, allows medical professionals to handle full-size, 3D objects printed from 3D scan data. There are also a wide range of educational uses. To date such products include automobiles, trainers, jewellery, plastic toys, coffee makers, and all sorts of plastic bottles, packaging and containers. Some dental labs have been using 3D printers to help create appliances for use in the creation of crowns, bridges and temporaries.

3D printing (also called Additive Manufacturing) uses successive layers of material which are laid down under computer control. The term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently the term’s meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering based processes and can use polymers or metals as the printed product.

As 3D products are becoming more common, one concern rises from the strength of the finished product and its ability to withstand tensile, compression, or impact forces of the real world applications. These properties are especially critical when they involve medical applications. To address this concern,  a recent start-up company has taken the proverbial bull by the horns and invested in an impact tester,  Tinius Olsen model  IT504, to ensure that the products they print can withstand the impact of daily life.

 
New Jersey’s Southern Regional School District Students Are Introduced to The Field of Materials Testing PDF Print E-mail
Monday, 09 March 2015 08:28

Tinius Olsen was invited to introduce some 7th /8th graders to the field of materials testing at the Southern Regional School District in Manahawkin, New Jersey last week. Regional salesperson Natalie Suchodolski took a low force testing machine and a bunch of commonly tested parts to the school and introduced students to the need to test products before they go to the market.

Says teacher Sue Stinson “They seemed to really enjoy the presentation and I can say for a fact that they have a new understanding as to the importance of materials testing, as well as possible career opportunities that were not in their previous mindset.”

“Given the fact that many of those students experienced home destruction by Superstorm Sandy,” continues Stinson, “and just the other day saw local damage due to an explosion, they see the need to testing the products on the market.”

 
How foam testing helps Automotive Companies PDF Print E-mail
Friday, 27 February 2015 08:31

Foams are widely used in the automotive industry to prevent injuries to passengers in the event of a collision. The use of foamed material results in a significant improvement in the passive safety of the vehicle, owing to their excellent energy absorption and dissipation properties. Additionally, they are relatively cheap and allow great design flexibility, as they can be easily modeled in complex geometric parts. Typical applications include door panels, instrument panels, armrest, inserts, glove box, seat backs, pillars, consoles, knee bolsters, water shields, air ducts and boot covers.

Benefits of foam in automotive applications:

  • Product flexibility
  • Wide thickness range
  • Flame retardant characteristics
  • High property values at low densities
  • Special vacuum forming and press moulding characteristics
  • Thermal Stability

 

Foam being an integral part of human safety needs to be of efficient quality to sustain the damages. Compressive strength of foam is the most important factor which determines the sustainability of foam. One of the global players from eastern America has recently started using the Tinius Olsen H5KT machine to test the compressive strength of foams.
