As seen from the above table, after increasing PMMA Yu PTFE, the most more apparent to the cladding of glass and the improvement on surface simultaneously.
After using the PC of extrusion grade, it is more favorable for reducing surface floating fiber phenomenon.The proportioning of itself PMMA Yu PTFE is to surface
Glossiness has certain impact, need to select suitable mix proportion scheme.Adjust the proportioning of PMMA Yu PTFE, available height
Light exempts from the in-dash computer material of spraying.Prove this be prepare a kind of high light exempt from spraying in-dash computer material have efficacious prescriptions
Method.
