ZeCai White Silicone Color Masterbatch for Consistent White Tinting in Silicone Rubber Production
| MOQ | 10 Kilogram |
| Category | Chemicals |
Product Description
This silicone color masterbatch is a high-end coloring raw material specially developed for silicone materials. It adopts high weather-resistant organic and inorganic pigments together with food-grade silicone carrier, and is refined through multiple processes including internal mixing, grinding and filtering. The pigments are fully dispersed, featuring high coloring concentration and fast tinting speed. After mixing, it rarely causes defects such as color particles, spots, flow marks and stripes, which stabilizes the surface appearance of finished goods and effectively reduces the rate of defective products.
It is compatible with platinum curing system, and shows excellent compatibility with solid compression-molded silicone, liquid injection silicone and extruded silicone. It will not affect the curing speed, nor damage the original physical properties of silicone such as elasticity, tensile strength and resilience. After molding, it features no migration, no bleeding and no blooming. There is no precipitation to contaminate contact surfaces during long-term use. It can withstand temperatures ranging from -60℃ to 230℃, with good resistance to yellowing and UV aging.
Product Advantages
- Excellent dispersion performance, uniform color distribution, no grainy spots on silicone surface
- Does not interfere with platinum vulcanization, keeps the original soft texture of silicone
- Stable color, good heat resistance and weather resistance, suitable for long-term outdoor use
- Non-toxic and eco-friendly, compliant with RoHS, FDA and LFGB standards for food contact scenarios
- Wide adaptability, works for solid silicone, liquid silicone and extrusion silicone
- Supports custom color matching according to customer samples
Application Range
Suitable for silicone kitchen utensils, silicone baby products, silicone seals, silicone tubes, silicone bracelets, silicone phone cases and all kinds of molded and extruded silicone consumer goods and industrial accessories.
