If the amount is less than 10 parts by weight, the resulting composition will have poor heat-resistant rigidity, which is undesirable. If it exceeds 90 parts by weight, the impact strength of the resulting composition will decrease, which is not preferred. The amount of propylene polymer (B) is 100% of the composition.
If the amount is less than 10 parts by weight, the resulting composition will become brittle, which is undesirable, while if it exceeds 90 parts by weight, the heat-resistant rigidity will be insufficient. If the amount of the inorganic filler (C) is less than 10 parts by weight in 100 parts by weight of the composition,
This is not preferable because the resulting heat-resistant rigidity is insufficient; on the other hand, 7
If the amount exceeds 0 parts by weight, the resulting composition becomes brittle, which is not preferable. If the amount of the α-olefin copolymer (D) is less than 3 parts by weight in 100 parts by weight of the composition, impact strength will not be improved, which is undesirable, while if it exceeds 20 parts by weight, heat-resistant rigidity will decrease, so it is not preferable. do not have.
