Generally speaking, PVC products with a plasticizer dosage of less than 10 PHR (indicates the mass fraction of the formula material required per 100 mass fractions of resin) are called hard products; PVC products with a plasticizer dosage of 10 to 40 PHR are called semi-hard products; and PVC products with a plasticizer dosage of more than 40 PHR are called soft products.

[0003] The calendering device is an important equipment in the production and processing of PVC plastic products. However, the existing calendering structure is relatively simple. During use, the height of the pressing roller cannot be adjusted according to the needs of the user, and it has great limitations when used.
