P-Type Carbon Black
Polymers, especially polyolefins like polyethylene, degrade when exposed to UV radiation from the sun in the presence of oxygen. The polymer chains undergo a radical reaction, leading to degradation and structural changes. For products that may be exposed to sunlight during storage or use (such as pipes), it is essential to incorporate UV protection materials through a proper mixing process with anti-UV materials. P-Type Carbon Black, due to its unique properties, can significantly contribute to the rubber industry by providing effective protection for polymers.
P-Type Carbon Black in the Rubber Industry
Properties: Due to its unique chemical structure, Carbon Black particles tend to cluster and adhere, necessitating a mixing process that ensures proper dispersion within polyethylene.
Applications: P-Type Carbon Black effectively addresses technical and quality issues in automotive rubber components. It plays a crucial role in producing sensitive extruded rubber parts and profiles and serves as a vital supplier to rubber and plastic factories.
