Polypropylene (PP-H) Thermal Expansion Coefficient

[PIPING_DESIGNER]

According to polypropylene PP-H pipes suppliers, the coefficient of thermal linear expansion is equal to 50*10^-6 in/in/F at 73°F.
Could you please give me this value at 176°F ?

Are pipe vendors unable to give you the information you need? I have to believe they have the data over a decent temperature range.
