The core secret of PVC tarpaulins lies in their PVC coated fabric technology. This material uses high-strength polyester canvas as the base fabric, and through a high-temperature plasticizing process, a uniform layer of polyvinyl chloride (PVC) paste resin is applied, along with additives such as mildew inhibitors and antistatic agents. The tight bond between the coating and the base fabric gives the tarpaulin the following unique properties:
100% Waterproof: The PVC coating forms a dense protective film, effectively preventing water penetration even after prolonged immersion or heavy rain, making it suitable for truck transportation, open-air warehouses, and other scenarios.
Tear and Abrasion Resistance: The double structure of the base fabric and coating gives the tarpaulin high strength and tear resistance, able to withstand external damage from cargo friction, hooks, etc.
Excellent Weather Resistance: Whether in severe cold of -20℃ or high-temperature exposure, the PVC coating remains stable and is not prone to aging or cracking.
The diverse functions of PVC tarpaulins make them the material of choice in multiple fields:
Truck Tarpaulins: Waterproof and sunproof, protecting goods from rain erosion.
Equipment Rain Covers: Covering machinery and electrical appliances to prevent rain and dust from entering.
Temporary Sheds: Quickly set up rainproof and windproof work areas.
Building Material Covers: Protecting rebar, cement, and other materials from weather damage.
Greenhouses: Regulating temperature and humidity, preventing rain and insects.
Storage Yard Covers: Covering large areas of goods to reduce losses.
Camping Tents: Lightweight and portable, adapting to complex outdoor environments.
Sunshades: Blocking ultraviolet rays and providing shade.
Temporary Shelters: Quickly setting up temporary shelters to withstand natural disasters.
To extend the lifespan of PVC tarpaulins, please note the following:
Cleaning Method: Wipe surface stains with clean water and a neutral detergent, avoiding strong acids and alkalis that can corrode the coating.
Storage Suggestions: Fold and store in a dry and ventilated place, avoiding prolonged exposure to sunlight which can cause fading and hardening.
Repair Techniques: Small areas of damage can be repaired with special glue; for large areas of damage, factory repair is recommended.
Although PVC tarpaulins have significant advantages, they should be used with caution in certain scenarios:
Environmental Concerns: The disposal of PVC materials after use may put pressure on the environment. In some scenarios with high environmental requirements, PE tarpaulins can be used as an alternative.
High Temperature Limitations: It softens easily at temperatures above 80°C, so avoid contact with high-temperature equipment.
