Product Description

Process characteristics
1. Poly (methyl methacrylate) contains polar methyl groups and has obvious hysteretic properties. Its water absorption rate is generally between 0.3% and 0.4%, and must be dried before forming.
2. Polymethyl methacrylate has effective and obvious non-Newtonian fluid characteristics in the temperature range of molding. The melt viscosity decreases with the increase of shear rate, and the melt viscosity is also sensitive to the change of temperature.Therefore, the melt viscosity and good fluidity can be obviously reduced by increasing the forming pressure and temperature in the forming process of POLYmethyl methacrylate.
3. The temperature at which polymethyl methacrylate began to flow was about 160℃, and the temperature at which it began to decompose was higher than 270℃, with a wide processing temperature range.
4. The melt viscosity of polymethyl methacrylate is higher, and the cooling rate is faster, and the product is easy to generate internal stress, so strict control requirements for the process conditions are required when forming, and the product also needs post-treatment after forming.
5. Poly (methyl methacrylate) is an amorphous polymer with a small shrinkage rate and its range of variation, generally around 0.5%-0.8%, which is conducive to molding plastic parts with high dimensional accuracy.
6. Poly (methyl methacrylate) has excellent cutting performance and its profiles can be easily machined to various required sizes.
The processing technology

Specification

Acrylic casting plate: high molecular weight, excellent stiffness, strength and excellent chemical resistance.This type of plate is characterized by small batch processing, unparalleled flexibility in color system and surface texture effect, and complete product specifications, suitable for a variety of special purposes.
Acrylic extrusion plate: compared with casting plate, the extrusion plate has lower molecular weight and slightly weaker mechanical properties.However, this feature is conducive to bending and thermal forming, and is conducive to rapid vacuum blister forming when dealing with large size plates.At the same time, the thickness tolerance of extruded plate is smaller than that of cast plate.Because extruded plate is mass automated production, color and specifications are inconvenient to adjust, so the diversity of product specifications are limited.
Acrylic board quality classification in the country is mainly divided into three categories: one is the import of the board;Second, Taiwan-funded board;Third, domestic plate.They differ in the origin and (MMA) purity of the raw materials used.This also is the key that decides the quality of plank and price.
