Plastoelastomer copolymers for geomembranes, roofing, sound dampening mats and carpet backing

Arkema Evatane® EVA and Lotryl® EMA can be used as flexible materials to incorporate rubber regrinds from tires or other sources of elastomers, to create eco-friendly dampening mats.

A stronger adhesion to some supports may be obtained with Orevac® or Lotader® reactive polyolefins.

Ambra guarantees a broad range of the main heat adhesive polyolefins which are used for any type of carpets and mats backing in constructions and automotive, both in the shape of granules to be micronized by the customer (Evatane® EVA or Lotryl® T EMA, EBA by Arkema) and tailor-made micronized powders with Ambra Powder, available in several colors and size distributions, and various mechanical, physical and chemical features.

Case Study

A unique sound dampening mat

Opportunity: A customer developed an exclusive proprietary technology to extrude sound dampening mats or sheets and membranes from composites made out of rubber tires regrinds plus polyolefins, and needed to optimize the properties of his final product by choice and concentration of the polymer.

Tip

In need for a proper adhesive powder for your insulation or dampening mat?

Ask for the right tailor-made combination of material and granule size distribution to Ambra with its Ambra Powder portfolio for dot gluing.

Breathability

Ambra technical Solutions for continous flexible films for insulation and sound dampening with high WVTR (Water Vapor Transmission Rate) include

•vapor permeable polymers (Sipol Sipolprene® block copolyesters, Arkema Lotryl® and Lotryl® T EMA copolymers)

•adhesive layers for extrusion coating onto non-woven fleeces (Arkema Evatane®, Orevac®, Lotryl® and Lotader®).

This makes Ambra a perfect partner to develop highly complex multi-layer breathable membrane structures for roofing, insulation, geomembranes, sound dampening and many other applications.

A breathable roof insulation membrane

Opportunity: Breathable roof building insulation membrane on woven-non-woven fabric.

Tip

Ambra is your partner for breathable insulation

Verify our full range of breathable polymers, from Sipol Sipolprene® block copolyester to Lotryl® and Lotryl® T EMA copolymers. With very high WVTR (Water Vapor Transmission Rate), water and microbial growth barrier properties of the continuous, non-porous film, tear resistance and UV resistance, we will surely find the best choice for your breathable, water-barrier house wrapping.

Gas-barrier

Arkema Evasin® EVOH polymer resin has the highest oxygen-barrier properties. But some may not know that Evasin® has great barrier properties also against many other gases, such as those stemming from industrial production or stocking, environmental pollution, etc.

On the other hand Evasin® shows very high WVTR, and thus it can be combined with Arkema tie-layers (Evatane® EVA, Lotryl® and Lotryl® T EMA, or Orevac® and Lotader® reactive polyolefins) or Sipol Sipolprene® TPC-ET for extrusion coating on non-woven support for complex membranes with breathable plus gas-barrier features, e.g. versus oxygen, radon, industrial gases, polluting vapors, etc.

Case Study

A gas-barrier, breathable geomembrane

Opportunity: For his complex gas-barrier, breathable insulation membrane for construction, a customer one day asked us to decrease our price and we would kick out competition.

Rigid insulating sheets and foams

A large variety of grades for rigid sheet extrusion and foaming for sound dampening is available by Lotte Starex® ABS with specific extrusion grades.

Mesgo has a focus on flame retardant (halogen and halogen-free), conductive (carbon black) and mineral filled compounds or concentrated masterbatches on various thermoplastics: Altair® PE, Avior® PP, Izar® PS, ABS.

Mesgo also has a core-competence in flame retardant masterbatches with its SwingAdd® Halogen, Low-Halogen and Halogen-Free.

Mesgo SwingAdd® additive masterbatches help to reduce the temperature degradation, improve the lifetime on UV and oxidation exposure, improve polymer processability, scratch resistance. SwingAdd® are available as single-function additives or as a combined proprieties or colors (combi-batches).

Jazzwhite® and Tangoblack® masterbatches are produced in large volumes at Mesgo Grigno plant, and they show very high concentration and excellent dispersion of the pigments on polyolefins, styrenics, PA and other engineering polymers at very reasonable costs. Color masterbatches are produced at Mesgo Iride Colors, with very high flexibility also for small batches.

For rigid or flexible sheets inherently flame retardant PVC compounds from TPV Compound are the first choice.

Virgin or recycled PP/mineral filled are available with Meplen® or EcoMeplen® by Mepol. Mepol also developed a range of recycled EcoMepron® PS and EcoMeplac® ABS.

Tailor-made formulations and colors – even for small batches – are also available with ColorTech Teclene® PP, Tecstir® PS and Teclan® ABS.

Flexibilization and impact increase in rigid insulation materials (PS, ABS, PVC) is obtained by direct addition of Arkema Evatane® EVA or Lotryl® EMA, or Sipol Sipolprene® thermoplastic block copolyesters. Ambra Impact PO may be used for recycled styrenics.

Basic polyolefins and polyolefin virgin resins and compounds with special offers, off-specs or slow movings from major world producers are available at Speedy Polymers.

Other solutions for rigid sheets and foam extrusion can be found under the Section: “EXTRUSION, FOAMING, THERMOFORMING, SHOES (NON-PACKAGING)” of Ambra Applications & Solutions.

Case Study

Helping cost competitiveness on GPPS foam insulation

Opportunity: Customer makes GPPS foaming for rigid membranes in construction insulation. He modifies flexibility by admixing SBS rubber. However, the high cost and high loading of SBS did not allow him to be competitive to gain new market share.

Improving odor properties of recycled plastics

Post-production and post-consumer plastic regrinds are more and more used in insulation, also in view of the new European and local national regulations on the increase of recycled content in plastics. This challenges manufacturers of membranes with improving odor properties.

Ambra Upgrade MBF is a range of odor covering, ready-to-use masterbatches based on Pollena Aroma® fragrances and Arkema Evatane® EVA, which may be directly added during film or sheet extrusion.

Tip

Smelly recycled plastic?

Reduce the number of defects, increase productivity

4cleanpure® and 4cleanmix® by 4clean will help to increase both your quality and productivity for your highest-value films or sheets.

Tip

Will 4clean add costs or save your money?

Make a trial on your extruder with 4cleanpure® or 4cleanmix® and 4clean + Ambra technical staff. Then you may answer the dilemma easily.
