How many grades does the hardness of glue line divide?


The hardness of PVC materials is generally 0-99sa shore hardness tester.

60P is a formula used by Taiwan companies and Hong Kong companies.This method is unscientific.

Because the hardness of 60P of each rubber company is different, some differences of the same P number are more than 5SA.

60P is about 80SA.

The smaller the P value, the harder the hardness. On the contrary, the higher the P value is, the softer the hardness will be.
