| Product description: TEGOMER® H-Si 6440 P is a polyester modified siloxane which is delivered in pellet form with excellent compatibility in thermoplastic and duroplastic resins. Application: TEGOMER® H-Si 6440 P is used as additive to improve the scratch resistance of engineering resins, TPEs and polyolefins. TEGOMER® H-Si 6440 P lowers the COF of materials such as TPE-Vs. TEGOMER® H-Si 6440 P is used for PA/GF and PP/GF based compounds. TEGOMER® H-Si 6440 P is used as compatible internal lubricant and release agent, e.g. mold release of SEBS based air bag covers. The additive is well suited to improve bulk and surface characteristics of final parts, especially notched impacts strength in filled polyolefins. TEGOMER® H-Si 6440 P can be used as additive for: - polyolefins
- polyamides
- polyesters/ polycarbonates
- thermoplastic elastomers
- thermosets
Benefits: TEGOMER® H-Si 6440 P used as an additive for polymer formulation. It improves the processing by: - better mould fill release behavior
- good internal lubrication
- improved rheology of polymer melt
The surface properties are improved by:- enhanced scratch and wear resistance
- lower surface frictions
- higher surface gloss
- better glass fiber wetting/ lower fiber brakes
It improves bulk properties by:- higher impact strength
- higher tensile strength
- reduction of brittleness
- hydrophobizing
