Injection molding process
AS processing temperature is generally preferably at 200-250 ℃
The melting temperature of 200-270 ℃ AS
Mold temperature of 40-80 ℃ AS
AS 350-1300bar injection pressure injection speed recommended speed injection
SAN (AS) has a strong ability to withstand load, anti-chemical reaction capability, thermal deformation characteristics and geometric stability. SAN (AS) in the glass fiber additives can increase the strength and thermal deformation, reducing the thermal expansion coefficient. SAN (AS) has a Vicat softening temperature of about 110 ℃. Deflection temperature under load is about 100 ℃. SAN (AS) of the shrinkage of about 0.3-0.7%. SAN (AS) is a hard, transparent material. The styrene content SAN (AS) hard, transparent and easy to process; acrylonitrile content the SAN (AS) having chemical stability and thermal stability.
