How to calculate the foaming ratio of EPE pearl cotton? EPE pearl cotton generally uses gram weight or density (kg / m3) to distinguish weight and model. But some customers also use the term "foaming ratio" in their communication. What is the "foaming ratio" of pearl cotton? The "foaming ratio" here refers to the "foaming ratio" of plastic raw material particles, such as polyethylene (LDPE) and o
EPE pearl cotton is the same, why is the difference so big? EPE (expand aple poly ethylene) is a kind of hair polyethylene, also known as pearl cotton. The production process of EPE is to take LDPE low density polyethylene resin as the main raw material, add foaming agent and anti shrinkage agent, and then extrude to make sheet. Freon is often used as foaming agent in the early EPE production pro
Pearl cotton foaming machine is mainly used to produce EPE pearl cotton sheet and profile. LDPE resin is melted and mixed with butane gas, talcum powder, anti shrinkage agent and other additives. It is extruded by extruder and foamed in die head and die lip, then fixed sheet size by setting ring. The final product is rolled by receiving roller. Working principle of pearl cotton foaming machine: p
Foaming method of EPE products EPE foaming products are widely used in our life. They are all made of EPE foaming. What is the foaming method of EPE foaming? The physical foaming method of EPE foaming products: the low boiling point liquid dissolved in polymer melt is evaporated to make it vaporized and foamed, or the inert gas can be dissolved in the plastic melt or paste under pressure, and th
Pearl cotton foaming machine is mainly used to produce EPE sheet. LDPE resin is melted and mixed with butane gas, talcum powder, anti shrinkage agent and its color masterbatch. It is extruded by extruder and foamed at die head and die lip. Then it passes through setting circle to fix sheet size. The final product is rolled by receiving roller. Can be made into a variety of sizes and thickness of p
do you know what is Pearl cotton(EPE) Polyethylene foamed cotton is a non-crosslinked closed cell structure, also known as EPE pearl cotton. It is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene grease through physical foaming to produce countless independent bubbles. It overcomes the shortcomings of ordinary styrofoam, such as fragility, defo
Analysis of the development trend of PVC rubber floor mats Rubber floor mats are made of natural rubber, synthetic rubber and other polymer materials. The natural rubber used in its production refers to the rubber cut from the artificial rubber tree, while the artificial rubber is a by-product of oil. Because all materials of rubber floor mats are non-toxic and harmless, rubber floor mats belong
Two kinds of materials have their own advantages! Good TPR flexibility, good Bai feel, no Du poison and environmental protection PVC has good strength, memory function, fire resistance and wear resistance Each has its own advantages that the other does not At present, the market of TPR and TPE is becoming larger and larger, and Dao has replaced many applications of inner PVC. The main reason l
