The long-term use temperature of PET preform mould can reach 120 ℃, and its electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance, creep resistance, fatigue resistance, and friction resistance are poor. ,

PET preform mould is designed by 3D computer drawing, which can be matched with various brands of machines at home and abroad. Molds for PET easy-open cans, mineral water bottles, hot-filling bottles, carbonated beverage bottles, liquor packaging boxes, etc. What are the characteristics of PET prefo

The unique design of the PET preform moulds eliminates the need to cool and reheat the hot runner during part changes, thus significantly reducing system downtime. It also reduces costs by minimizing the number of components to replace, while easily adapting to any preform length. Replacement time c

PVC compound for pipe fitting is polymerized from polyvinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging, acid and alkali resistance, and is very suitable for chemical pipelines. The mixture composed of a certain amount of solid additives (without plasticizers) added to the raw materials of polyvinyl chloride is called rigid polyvinyl chloride (UPVC).

PVC compound for pipe fitting cannot be hot-melted, and its sealing performance is not good; it is a rigid pipe material and has poor shock resistance; it often contains free chlorine, and its value itself is thermally stable.

In modern life, plastic building drainage pipes, water pipes and sewage pipes have been widely used, and polyethylene pipes are becoming the development direction of plastic pipes. PVC compound for pipe fitting was first used by Germany in 1936, and the world's first plastic water pipeline was laid in Britain in 1939. Since then, plastic pipes have developed rapidly, constantly replacing metal pipes or other traditional pipes. In the 1970s, the standardization and serialization of PVC compound for pipe fitting was realized internationally, which greatly promoted the production and application of plastic pipes in various countries.
