PS Plastic Cable spool (polystyrene),
material performance: electrical insulation (especially high -frequency
insulation) excellent, colorless transparency, secondary light transparency,
second only to organic glass, coloring water resistance, good chemical
stability, strength, strength. Generally, crispy, easy to produce stress crispy
cracks, is not resistant to organic solvents such as benzene gasoline. Suitable
for making insulation transparency, decorative parts and chemical instruments.
Optical instruments and other parts.
1. No fixed -shaped material, small water
absorption, no need to dry, not easy to decompose, but the thermal expansion
coefficient is large, it is easy to produce internal stress. The liquidity is
better.
2. It is advisable to use high material
temperature, high -modular temperature, low injection pressure, extending the
injection time is conducive to reducing the internal stress and preventing
shrinkage. Deformation.
3. You can use various forms to pour the
mouth, pour the mouth and connect with the plastic piece, so as not to damage
the plastic parts when the mouth is poured. If there are inlaid, preheat.
ABS Cable Spool (acrylate-butadiene-lye) is
a light yellow granular or pearly opaque resin, which is non-toxic, tasteless,
and low water absorption. It has excellent physical and mechanical properties,
excellent low temperature resistance impact performance, excellent electrical
properties, abrasion resistance, size stability, chemical resistance, and dyeing.
Easy to process. ABS water -resistant, inorganic salts, alkali and acids are
insoluble in most alcohol and hydrocarbon solvents, and are easily soluble in
aldehyde, ketones, esters and certain chlorine chloride. The disadvantages of
ABS are combustible, the thermal deformation temperature is low, and the
patient is poor. Features of combustion: flammable; continued burning; flame
yellow, thick black smoke; softening, foaming; acrylic flavor. Soluble
performance: soluble solvent: dichloromethane; insoluble solvents: alcohol,
fatty hydrocarbons, water. Application: automotive industry, mechanical
equipment, electronic appliances, etc.
