ELASTOMERS THERMOPLASTICS
1. FELPRENE
Felprenes have a very good resistance to abrasion and an exceptional flexibility at low temperatures. The vast range of additives and olefins incorporated in our compounds has allowed us to create a large diversity of products that can replace either PVC elastomers in the shoe industry or natural rubber in the waterproof joints industy. Some similar products are Santoprene (TPV) and Monprene. Their affinity for PS, ABS or SAN make the Felprene class of Thermoplastic Elastomers an alternative to be considered in the choice of materials for casting and co-extrusion. We offer an extensive array of colors and hardness factors.
Felprenes are products that have SBS as the base ingredient, a molecule made up of a supple butadiene segment joined by two hard segments of styrene at its extremities. The supple segment gives the product its elastomeric properties, whereas the rigid segments create bridges amongst the molecules in the cooling phase, thus creating a three dimensional network. The styrene segments are what give the material its thermoplastic properties.
2. EPRENE
We offer materials from this class of products that can replace natural rubber and TPV (Vulcanized thermoplastics, type Santoprene) as well as similar products such as Synprene, Santoprene and Sarlink.
The products that are part of the Eprene family are compatible with Polypropylene, and are therefore used for casting. The fact that they are impervious to UV rays makes them a good choice in outdoor applications that demand a good resistance to oxidizing agents.
The Eprene family is a class of products that has SEBS as the base ingredient. SEBS is a product that is in turn obtained from SBS. It has an advantage compared to SBS because the molecule contains no double bonds, which are naturally sensitive to oxidation phenomena. SEBS is therefore particularly resistant to oxidation and is a material that is well adapted to applications that are demanding in terms of heat, UV lighting, ozone and oxidizing chemical agents.
3. SEPRENE
The major application for the Seprene family of products is for the construction industry (industrial boots, etc.) and for the automobile industry. They are also used to replace santoprene, sarlink, tekbond and synprene.
The elastomeric base is a hydrogenated isoprene. This compound is compatible with polyolefin, and it is therefore possible to cast polypropylene or co-extrude these products. Also, it has very good adhesion properties to other plastics.
The Seprene family of products represents a class of special elastomers that meet some of the most demanding requirements such as: resistance to chemical products, compression at low temperatures and oil absorbance.
4. CELPRENE
The Celprene family of products includes expanded thermoplastic elastomers.
The products developed have EVA, polyolefins or SBC copolymers as the base ingredient. The ‘foamed’ product can be either cross-linked or structural foam.
