THERMOPLASTIC ELASTOMERS

thermo-elasto-felprene

1.FELPRENE (TPR, SBS) see Technical Data Sheet
Felprene offers high resistance to abrasion and exceptional flexibility in low temperatures. The wide range of additives and olefins incorporated in our compounds have allowed us to create a vast selection of products that can replace either elastomer PVC used in footwear or natural rubber in manufactured gaskets and seals. Some similar products include Vistaflex, Garaflex, and Tekbond. With its strong affinity with PS, ABS, or SAN, the Felprene class should be considered as an alternative when selecting compounds for over-molding or coextrusion. These products are available in an extensive variety of colours and hardness values.

The base ingredient of Felprene is SBS, a copolymer composed of a soft segment (butadiene) to which are attached two hard segments (styrene) at the extremities. Example: Kraton D

2. EPRENE (TPE SEBS) see Technical Data Sheet
The Eprene class consists of products that can replace natural rubber and TPV (vulcanized thermoplastic), as well as similar products like Synprene, Santoprene, and Sarlink.

Products included in this class are compatible with polypropylene, and are used for over-molding and extrusion. Their resistance to UV rays makes them the ideal choice for outdoor applications that require a high resistance to oxidizing agents.

These products are mainly used for footwear, profiles, construction, toys, “soft touch” and commodities.

Eprene-class products are formulated from SEBS. Contrary to SBS, SEBS does not contain double bonds (by nature sensitive to oxidation), making it especially resistant to wear. It is therefore perfectly suited for harsh conditions involving heat, ultraviolet radiation, ozone, or oxydizing agents. Example: Kraton G

3. SEPRENE (TPE SEEPS) see Technical Data Sheet
Seprene represents a class of special elastomers that meet the most specific requirements, for instance, resistance to chemicals, compression, or low temperatures, oil retention, etc. The elastomer base is a hydrogenated isoprene.
Due to its high compatibility with polyolefins (PP, PE), this compound is recommended for over-molding and coextrusion of these products. It also shows a very good adhesion to other types of plastic (nylon, ABS, TPU, PS).
These products are mainly used in construction, along with industrial footwear, automotive industry products, etc.

DIPRENE (TPO) see Technical Data Sheet
Compounds of the Diprene class are all based on EPDM. They are particularly suited for profiles extrusion and injection moulding.
Keeping their flexibility even when subjected to extreme temperatures, these compounds offer an excellent replacement solution to PVC and vulcanized rubber.
Diprene offer a very good value in terms of quality/price.
A non-polarized elastomer, it provides proven resistance to polarized solvents, acids, alkalies, water, and alcohol.

5. EXPANDED TPE
The blowing agent is contained in the compound; it is ready-to-use.
Products developed in this class are based on EVA and polyolefins or SBC (TPR, TPE, TPO) copolymers.
