BYK-MAX CT 4270

BYK-MAX CT 4270 by BYK is an organophilic phyllosilicate-based additive which provides ultra-efficient reinforcement to thermoplastic compounds. It is based on mixed morphology clay technology, which aids in compounding and dispersion. When added at <10% and preferably <6% by weight to a TPO or polyolefin composite, it allows for a lower total mineral content, lower final density, improved surface appearance, mold flow, dimensional stability and improved scratch resistance. The high reinforcement dramatically increases physical properties such as tensile strength. The target application areas include TPO-based automotive properties and traditional mineral or glass-filled composites. The BYK-MAX CT 4270 organic modification is designed to have greater thermal stability during processing. The use of co-rotating twin-screw extruders or a BUSS continuous kneader is recommended when compounding thermoplastics materials to achieve an optimum dispersion and exfoliation of the additive. Recommended dosage level is 3-6% additive (as supplied) based on the total formulation.
