Polypropylene Spec
Polypropylene Spec
(OP)
A machined plastic part designed and sourced in England lists the material as "thermally stabilized polypropylene". It has a smooth finish and an opaque biege/gray color. I want to make some parts from the same material, but I can not get a detailed spec from the UK supplier, and I can not find a source for this kind of polypropylene in the US. Supposedly, this material is common in the UK.
I got a sample of Propylux HS from Westlake Plastics. It is heat stabilized, but it is a bright white color and so does not match the beige/gray parts from the UK.
Any ideas how to identify and locate a source for this plastic?

RE: Polypropylene Spec
Can you use CPVC? A standard color is gray or light gray:

Thermally stabilized only means that it was annealed.
Flame retardant has an additive (I believe boric oxide) and has been UL tested.

Can you not arrange a colour match and order pre-coloured compounded material from any PP supplier and anneal the parts post moulding?

I use small quantities of small PP parts that are machined from PP sheet. Quanties are too small for custom mixing, matching or molding.
