PVC products can be generally divided into hard and soft categories. No plasticizer is added to the processing of hard products, and a large amount of plasticizer is added to the processing of soft products. PVC was originally a rigid plastic with a glass transition temperature of 80-85 °C. Adding plasticizers can lower the glass transition temperature, promote processing at lower temperatures, increase the flexibility and plasticity of molecular chains, and make elastic products at room temperature. The amount of plasticizer in soft PVC plastic is 30%-70% of PVC.
Plasticizers, stabilizers, lubricants, colorants and fillers can be processed into various profiles and products when added to PVC during processing.
How to identify product quality?
PVC trachea properties:
1. The transparent tube has high transparency and the state of the flow of the medium is clearly visible.
2. The pneumatic pipe has a small bending radius and is easier to install.
3. the yellowing resistance reaches the level of 3 or more, and is not easy to be yellow.
4. The color tube adopts the imported weatherproof color powder, the color standard of the color tube made is bright, long-term work does not fade.
5. Using on-line diameter control system, the tolerance of pipe diameter is controlled within ±0.12mm.
6. Made of 100% high physical plastic polyurethane elastomer (TPU) with constant working pressure and longer life.
7. Through SGS certification and ROHS certification.
Use of PVC tube: suitable for liquid transportation of general working pressure in industry, agriculture, food, medicine, civil engineering, fishery, aquaculture, garden irrigation and so on. For example: pneumatic pipe, hydraulic pipe, garden water pipe, oil transmission, water pipeline, oil exploration pipe, sand blasting pipe, peristaltic pump hose, etc.
Properties of PVC tubes:
1, good oil resistance, which is 15 times as high as that of natural rubber;
2, the wear resistance is good, and the abrasion resistance of the natural rubber is 30-50 times;
3, the aging resistance of natural rubber is 5 times higher than that of natural rubber;
4. The breaking strength of natural rubber is three times as strong as that of natural rubber.
5, with high elasticity, high elongation, high strength;
6, good damping property, smooth inner wall, small liquid resistance and less hydraulic loss;
7, beautiful appearance, small bending radius of hose, non-toxic and tasteless, impact resistance, fatigue resistance, lightweight and flexible, weight is 30% to 70 of rubber hose
8, good resistance, non-toxic and tasteless. Impact resistance, fatigue resistance, safety and reliability.
