To meet highest requirements
TERRA has years of experience in colorants for silicone rubber compounding, components, solid silicone rubber extrusion, compression molding, and liquid injection molding. Our colorants help manufacturers to reduce residual solvents and odors, and support simpler, less labor-intensive processing. They cover the full range of RTV, LSR and HTV silicone rubbers. They are high strength, low dosing, environmentally friendly, and show pumpable viscosity. They conform with American, European and Asian regulations, and California’s Proposition 65 Safe Drinking Water and Toxic Enforcement Act.
