Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a flexible, odorless and low-temperature-resistant PVC board. Background Art

[0002] PVC board is a board that is extruded using polyvinyl chloride as the main material. PVC board has many significant advantages, including chemical resistance, weather resistance, flame retardancy, light weight and high strength, easy processing and molding, as well as environmental health. Flexible, odorless and low-temperature resistant PVC board is a special PVC material that has good flexibility, odorlessness, and low-temperature resistance. This material is usually used in situations where it needs to be used in low-temperature environments, such as refrigeration equipment, frozen food packaging, etc. This type of PVC board is usually installed by splicing multiple PVC boards together as insulation materials in refrigerators or freezers. After long-term use, this type of PVC board may cause the connection between adjacent PVC boards to loosen due to the low temperature in the refrigerator or cold storage, resulting in the gap between adjacent PVC boards becoming larger and larger, and the thermal insulation performance of the PVC board also decreases. In view of this, we propose a flexible, odorless and low-temperature resistant PVC board. Utility Model Content
