Thus, working roller to perform uniform accurate grinding has not become true for roller surface rigidity and ORG grinding wheel rigidity fluctuating result in excessive or deficient roller grinding.

Nucleating agent is a functional accessory ingredient of polyolefin that can improve the rigidity, transparency and surface gloss of polyolefin products.

It should have high surface precision and enough intensity and rigidity. But the limited space and weight target make the contradictions between space and rigidity, rigidity and weight.
