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.
