Overview of PVC Films supplier
In the production, we add the main component of PVC films supplier, which is polyvinyl chloride resin, and other additives such as plasticizers (like phthalates to increase flexibility), stabilizers (like calcium and zinc stabilizers to prevent degradation), and lubricants (like stearic acids to reduce friction and improve luster).
Differences between PVC and Other Film Materials
PET Films or PVC films
- Concept and Appearance Differences: Suppliers make PVC from polyvinyl chloride. It is relatively hard in quality and can range from transparent to opaque. People make PET from polyethylene terephthalate. Firstly, it has a transparent surface. Secondly, property differences, PVC films have high requirements for heat sources, are low-cost, and have a medium shrinkage rate. PET films have a gentle change in temperature and shrinkage, with a maximum shrinkage rate of up to 80%.
- Environmental Performance Differences: When burned, PVC produces acidic substances. These substances are not environmentally friendly, so their use is restricted in some countries. PET is environmentally friendly and healthy.
- Usage Differences: PVC is mainly used in pipes, toys, etc. PET is commonly used in the electronics, automotive and other industries.
- Other Characteristic Differences: PVC films have good flexibility, acid – and alkali – resistance, etc. PET films have high strength, high transparency, good tear resistance, heat resistance, and weather resistance.
PP Films
- Composition Differences: PP films are made of polypropylene, while PVC films are made of polyvinyl chloride.
- Characteristic Differences: PP films have high heat resistance, relatively high strength, and hardness. PVC films have relatively high gloss and transparency and good insulation properties.
- Performance Differences: PP films have good mechanical properties and strong corrosion resistance. PVC films have weather resistance, light transmittance, anti – static and other functions, and strong scratch – proof ability.
PE Films
- Material Property Differences: People make PE films from polyethylene, and they have high flexibility and cold resistance. People make PVC films from polyvinyl chloride, and they have high hardness and heat resistance.
- Manufacturing Process Differences: The production process of PE films is relatively simple, using the extrusion process. The manufacturing of PVC films is more complicated, with multiple processing methods.
- Environmental Friendliness Differences: People make PE films green and environmentally friendly, and recycle them. PVC films may release organic substances during processing and use, with pollution risks.
- Physical Performance Differences: PE films have good tear resistance and transparency. PVC films have good acid – and alkali – resistance and electrical insulation performance.
- Price Differences: PE films have low production costs and are affordable. PVC films have relatively high production costs and are relatively more expensive.
Analysis and Application Recommendations
People state that PVC films and other film materials have advantages and disadvantages. In practical applications, people should select appropriate film materials according to specific requirements and applicability to meet different technical and environmental requirements.
