What is the material PMMA
What is the material PMMA The chemical name is polymethyl methacrylate, and the English name is simply PMMA PMMA name: Hong Kong people called PMMA acrylic acid glue, mainland China called acrylic acid or plexiglass. Acrylic has a transparent height and is one of the alternatives to glass. PMMA stands for polymethyl methacrylate, which is
What are the plastic materials that meet food-grade safety?
Food-grade safety plastic material classification: I. PET 1, PET plastic is often used to make plastic bottles, beverage bottles and other products, people often buy plastic mineral water bottles, carbonated beverage bottles are PET packaging products, belong to the food-grade safety plastic material. 2, safety risks: PET is only suitable for room temperature or cold
What are the characteristics of pmma plastic and the process?
pmma plastic characteristics PMMA processing requirements are more stringent, it is sensitive to water and temperature, to be fully dried before processing (recommended drying conditions for 90 ℃, 2 ~ 4 hours), its melt viscosity is large, need to be higher (225-245 ℃) and pressure molding, mold temperature at 65-80 ℃ is better. PMMA stability
What are the advantages of thermoplastic elastomer TPE/TPR compared to PVC?
Thermoplastic elastomers TPE/TPR and PVC are both soft, hardness-adjustable polymers. It is difficult to distinguish them by the naked eye alone, and the application fields of the two types of materials can be said to be relatively similar, but soft rubber TPE/TPR for some readers may not be as familiar with PVC plastic, today, briefly,
TPE extrusion products nine quality problems cause analysis
TPE (Thermoplastic Elastomer) extrusion products are widely used in various industries due to their excellent properties such as flexibility, durability, and resistance to impact and weather. However, there are several quality problems that can arise during the extrusion process. Here are nine common quality problems with TPE extrusion products and their possible causes: A. Insufficient

How do plastic extrusion machines work?
Plastic extrusion machines are used to create a variety of plastic products, including tubes, pipes, sheets, and films. These machines work by melting plastic material and then shaping it into a desired form using a die or mold. Here is a general overview of how plastic extrusion machines work: Material feeding: The plastic material, typically
