-
The super strong plasticizing high molecular weight PVC foaming regulator LX-530/LX-80 is a fully acrylic PVC high molecular weight foaming regulator independently developed by the company to meet the increasing demand for PVC extruded micro-foaming materials; it can be applied in various foamed profiles, pipes, sheets, wood-plastic, large plates, wall panels, and large-diameter corrugated pipe products; the ultra-high molecular weight is prepared from acrylic monomers through an ultra-low temperature emulsion polymerization process, with a high content of hard monomer components, belonging to random copolymers, with ultra-high molecular weight and linear distribution, and can be widely used in billboards, high-filled foamed profiles, bathroom cabinet boards, density boards, foamed thick plates, extra-thick plates, wood-plastic, construction templates, etc. The products are all white powders, insoluble in water and ethanol, and can dissolve or swell in ethers, ketones, and chlorinated hydrocarbons. The products meet the hygiene standard GB9681.

Product Advantages
❊ The ultra-high molecular weight product can promote the low-temperature melting of PVC, effectively changing the rheological properties of PVC products.
❊ The ultra-high molecular weight and ultra-strong melt strength can effectively prevent the fusion of bubbles and the rupture of bubble walls, resulting in a uniform and dense bubble structure, with low product density.
❊ Prevent bubble melting and rupture.
❊ The high content of methyl methacrylate monomer in ultra-high molecular weight products has a glass transition temperature close to polymethyl methacrylate (acrylic). It has excellent compatibility with PVC, providing the PVC melt with excellent melt strength while the foaming agent releases gas when heated, and has strong and stable coating ability.
❊ Significantly improves the thermal elongation and elasticity of PVC products.
