1. Mechanical Njirimara: PS bụ ihe siri ike na nke na-adịghị ike nke nwere obere ductility na-adịghị ekwenye ekwenye mgbe agbatị.Ihe eji arụ ọrụ nke polystyrene jikọtara ya na usoro njikọ, oke molecular ikwu, okpomọkụ, ọdịnaya adịghị ọcha na ụzọ nnwale.

2. Thermal Njirimara: PS nwere adịghị mma na-eguzogide okpomọkụ, na okpomọkụ deformation okpomọkụ nke 70 ka 95 Celsius C na ogologo oge ojiji okpomọkụ nke 60 ka 80 ° C.Ya mere,serological pipettesenweghị ike igba ogwu site na oke okpomọkụ na nrụgide dị elu, a na-ahọrọkwa ịgba ọgwụ mgbochi radieshon.The thermal conductivity nke polystyrene dị ala, banyere 0.10 ~ 0.13W / (m·K), na ọ dịghị agbanwe agbanwe na okpomọkụ mgbanwe.Ọ bụ ezigbo ihe mkpuchi ọkụ.

3. Ngwa eletriki: PS bụ polymer na-abụghị polar, na ole na ole fillers na mgbakwunye na-agbakwunyere n'oge eji.Ya mere, ọ nwere ezigbo dielectric Njirimara na mkpuchi, na dielectric Njirimara ya enweghị ihe jikọrọ ya na ugboro ugboro.
