Application of talc powder in polyethylene resin

Talc is natural magnesium silicate, its unique micro-scale structure, with certain water resistance and high chemical inertness, so it has good chemical resistance and slidability. It can be used as an engineering plastic with polyethylene. It has good chemical resistance and fluidity and can compete with ABS, nylon and polycarbonate. Filling polyethylene with it can improve the following properties: increase toughness, flexural modulus and twist modulus; increase flexural strength; reduce creep tendency at normal temperature and high temperature; increase thermal transition temperature and dimensional stability; improve deformation And warpage, but also has a low coefficient of thermal expansion; improve thermal conductivity; improve the surface hardness and smoothness of molded parts; improve the mechanical strength of polyethylene. Adding different proportions of talc powder will have different effects on the physical properties of polyethylene materials, and the addition ratio is optimal at 10-15%. For polyethylene blown film, the superfine talc powder masterbatch is better than other fillers, easy to form and good in processability. Moreover, the film can reduce the oxygen transmission rate by 80%, and is particularly suitable for packaging oily foods, such as peanuts, broad beans, etc., and maintains no oil for a long time, and does not deteriorate: the film can reduce the water vapor transmission rate by 70%. It has good moisture resistance and is suitable for underground geotextile moisture-proof cloth. It is also suitable for packaged food.
