PVC hoses will become hard in winter. This is due to the characteristics of PVC plastics. It will become hard when it is cold, which is a normal physical phenomenon. During the production process, the formula is usually adjusted according to the season, and it will be adjusted to the winter formula after October to meet market demand.
Reasons for PVC hoses to become hard
PVC hoses become hard in winter mainly because the temperature drops and the plastic material becomes harder. This is a characteristic of plastics, which is the same as preheating and softening. In northern regions, PVC hoses are more likely to encounter the problem of hardening.
Measures to deal with the hardening of PVC hoses
Use winter formula: During the production process, the formula can be adjusted and more plasticizers can be added appropriately to keep the hose relatively soft in winter.
Choose the right material: Some PVC hoses use a thickened design and tendon structure, which can remain soft even in cold weather and will not harden or burst.
Use cold-resistant plasticizers: Although the use of cold-resistant plasticizers can help hoses remain soft at low temperatures, it may increase costs and may cause oil leakage risks.
