Best plastic material/ grade for Plastic Pallet 1

[Thanh_fromVietnam]

Hello, I am working at a company that produces plastic pallets using injection molding technology
i am using HDPE plastic and looking for alternative material that can be injection molded and have better impact resistance, cold resistance performance. For example, PP copolymer
I have tested the production of plastic pallets using PP copolymer, resulting in an excellent pallet product in terms of impact resistance, but HDPE is more commonly used for pallets on the market. and did not find any advantages of HDPE plastic compared to PP copolymer plastic. So why do other manufacturers rarely use PP copolymer plastic for pallet products?
Looking forward to everyone's discussion.

maybe chemical resistance?
maybe thermal stability/deflection?

90% of engineering decisions come down to cost.
