|---|
| VELVEX™ 5250 is a reinforced elastomer/ PP compound which provides a unique property balance of good stiffness, impact and high heat resistance in combination with a pleasant soft touch, low CLTE and easy processing. Very uniform low gloss is achieved in combination with outstanding scratch and mar resistance. VELVEX™ 5250 is either available: as factory coloured VELVEX™ 5250 ESU or as natural VELVEX™ 5250 SC Natural in combination with the colour concentrate CC REUV4%.&& |
