Differences Between 500gsm and 900gsm PVC Coated Fabrics

Introduction

PVC (polyvinyl chloride) coated fabric is a functional material created by uniformly coating a base fabric (such as polyester or nylon) with PVC resin using a special process. The PVC coating forms a dense protective film that resists rainwater and oil stains.

PVC coated fabrics are widely used in luggage, tents, car tarpaulins, medical protective clothing, and other fields, and are common materials in industrial and civil applications.

Differences Between 500gsm and 900gsm PVC Coated Fabrics

1. Gram Weight and Physical Characteristics

500gsm: The fabric weighs 500 grams per square meter, a medium thickness that balances lightness and basic protection.

900gsm: The fabric weighs 900 grams per square meter, significantly thicker, with stronger abrasion resistance and tear resistance.

Differences: Feel: 900gsm is thicker, heavier, and stiffer, suitable for high-intensity use; 500gsm is moderately soft, easy to fold and store.

Thickness: 900gsm is usually about 30%-50% thicker than 500gsm, and can withstand scratches from sharper objects.

2. Performance Comparison

Performance Indicator 

Waterproof: suitable for daily splash protection High waterproof rating, no water penetration even after prolonged immersion

Abrasion Resistance: Suitable for medium friction scenarios Abrasion resistance index increased by more than 50%

Tear Resistance: Medium transverse tear strength, excellent performance in both longitudinal and transverse directions

Weather Resistance: can withstand general ultraviolet rays Anti-aging formula extends service life

3. Differences in Application Scenarios

500gsm: Daily luggage: backpacks, travel bags, balancing lightweight design and waterproof needs.

Lightweight outdoor equipment: camping mats, sunshades, suitable for short-term use.

Home decoration: waterproof tablecloths, sofa covers, easy to clean and maintain. 900gsm: Industrial Protection: Truck tarpaulins, construction site enclosures, requiring long-term weather resistance and abrasion resistance.

Professional Outdoor Use: Mountaineering tents, rescue equipment, for extreme weather conditions.

Medical Field: Antibacterial isolation curtains, surgical gowns, requiring high-strength protection.

How to choose the right PVC coated fabric?

Clarify the usage scenario: Daily commuting or short trips → 500gsm.

Industrial protection or outdoor adventures → 900gsm.

Consider additional functions: If flame retardancy or antibacterial properties are required, prioritize 900gsm and confirm whether it contains flame retardants or silver ion coating.

Balance budget and durability: For high-frequency use scenarios (such as logistics transportation), it is recommended to invest in 900gsm to reduce replacement frequency.

Conclusion

The core difference between 500gsm and 900gsm PVC coated fabrics lies in the performance differences resulting from the weight. Users need to find a balance between cost, function, and durability based on their actual needs.
