Additive for thermoplastic compounds: BYK-MAX CT 4270

Organic modified layered silicates (clay materials) that impart reinforcing effects to thermoplastic compounds.

BYK-MAX CT 4270 allows for improvements in low density, surface appearance, flow length, dimensional stability, and scratch resistance by being added to TPO or polyolefin compounds in amounts of less than 10 weight percent, preferably less than 6 weight percent. It also enhances mechanical properties such as tensile strength. The intended applications are inorganic fillers or glass-filled compounds for TPO-based automotive parts. Unlike other commercially available clay products, BYK-MAX CT 4270 is based on mixed-form clay technology, which facilitates easy dispersion. The organic modification of BYK-MAX CT 4270 is designed to withstand thermal history in the compound. Our proprietary mixed-form clay exhibits excellent dispersibility. Additionally, changes in melt rheology can improve flow length within the mold and reduce resin temperature, leading to shorter cycle times. In composite formulations, a resin-rich surface is often observed. While increasing tensile strength, it is important to note that BYK-MAX CT 4270 may reduce impact strength. To avoid this, a comprehensive evaluation of the entire formulation is necessary. Blending with impact modifiers in the base resin is crucial for achieving the final performance results.
