SX molding compounds standard grades£º
There are 4 Standard grades, with properties and applications as follows:

 

SX-301
Molding compound with good flow property and normal heat resistence.
Application: the products with complicated shape and long molding path, such as crafts and housewares.

SX-302
Molding compound with normal flow property, good heat resistence and mechanical strength.
Application: the products with simple shape and requiring good heat resistence, such as magnifying glass, nameplate, indicator and container.

SX-303
Molding compound with excellent heat resistence, mechanical strength and good light transmission, low flow property than SX-302.
Application: Injection molding compounds, such as automobile instruments and lamps

SX-304
Molding compound with excellent heat resistence, mechanical strength, and light transmission up to 93%
Application: LGP (light guide panel)
