General Purpose Silicone Rubber For Molding
Compound general-purpose silicone rubber is a versatile, high-performance silicone rubber material designed to meet the comprehensive needs of industrial and consumer products for temperature resistance, safety and processing flexibility. Through optimized formula, the product has excellent performance in vulcanization efficiency, mechanical strength and environmental performance. It is suitable for a variety of production processes such as extrusion, compression molding, injection molding, etc., and has passed ROHS/REACH/LFGB/FDA multiple certifications, and can be safely used in harsh scenarios such as food contact and medical equipment.
Product Advantages
1. Efficient vulcanization & stable physical properties:The vulcanization speed is increased by 30% (175℃ ×5min×15MPa), supporting rapid and continuous production.Hardness covers Shore A 20-80, tensile strength ≥6-8MPa, tear strength ≥15-25kN/m, meeting diversified strength requirements.
2. Ultra-wide temperature range adaptability:Long-term use temperature -50℃~250℃, short-term temperature resistance up to 300℃, excellent anti-aging performance (175℃ ×22h compression permanent deformation ≤10%).
3. Environmental protection and safety:No heavy metals added, passed ROHS/REACH/LFGB test, in line with food grade (FDA) and medical device contact standards.
4. Processing friendliness:Excellent fluidity, adjustable plasticity 100~280, suitable for high-precision molds and complex structure molding, the finished product surface is smooth and free of bubbles.
