The role of methyl tin stabilizer
Methyl tin stabilizer is an efficient heat stabilizer mainly used in the thermal processing of polyvinyl chloride (PVC). Its main functions include:
Thermal stability: Methyl tin stabilizers have excellent thermal stability and can maintain the physical and chemical properties of PVC unchanged under high temperature conditions, preventing PVC from degrading during processing.
Transparency: PVC products stabilized with methyl tin can maintain high transparency without whitening, making it ideal for manufacturing transparent products.
Compatibility: Methyl tin has good compatibility with PVC and is easily dispersed in PVC complexes. It will not precipitate even after long-term use, thus not affecting the surface properties and electrical properties of the product.
Liquidity: Methyl tin can improve the melting effect of PVC, making it have good fluidity during processing, reducing melting viscosity, and helping to improve production efficiency.
Non toxicity: Methyl tin stabilizer is considered a non-toxic and environmentally friendly stabilizer, with minimal migration in PVC. It has been recognized by multiple countries and organizations and can be used in high hygiene requirements such as food and pharmaceutical packaging.
The use of methyl tin stabilizer
Methyl tin stabilizer is widely used in the production of various PVC products due to its excellent performance, mainly including:
Food packaging: Due to its non toxicity and high safety, methyl tin stabilizers are widely used in the manufacture of food packaging materials, such as packaging films, containers, etc.
Pharmaceutical packaging: Methyl tin stabilizers are also used in the manufacturing of pharmaceutical packaging materials, such as infusion sets, to ensure the safety and stability of products.
Water supply pipe: Methyl tin stabilizer can be used to manufacture water supply pipes, ensuring that water quality is not contaminated and guaranteeing drinking water safety.
Building decoration materials: In the fields of plastic doors and windows, decorative materials, etc., methyl tin stabilizers are used to replace other highly toxic plastic heat stabilizers.
Rigid PVC products: Methyltin stabilizer is applicable to all PVC homopolymers, such as lotion, suspended solids and bulk PVC, as well as copolymers, graft polymers and copolymers of PVC, and is widely used to manufacture rigid PVC films, sheets, plates, pipes, pipe fittings and profiles.
High definition products: Methyl tin stabilizers are particularly suitable for manufacturing high-definition hard PVC products, such as transparent sheets, boards, heat shrink films, etc.
In summary, methyl tin stabilizers play an important role in the PVC processing industry due to their excellent thermal stability, transparency, compatibility, and non toxicity, especially in the fields of food packaging, pharmaceutical packaging, and high-definition products, with broad application prospects.
