Geotextiles Application
Geotextiles are a new type of geotechnical engineering material made from various polymers and used in construction and environmental projects. These materials are strategically placed inside, on the surface, or between soil layers to serve functions such as reinforcement, filtration, drainage, impermeability, separation, and protection. The main raw materials for manufacturing geotextiles include polyester fiber (PET), polypropylene fiber (PP), and polyamide fiber (nylon). Among these, polyester is the most widely used, followed by polypropylene.
Due to the fine fiber structure and the long-term exposure to outdoor conditions, geotextiles are prone to photooxidative degradation, which results in fading, embrittlement, and mechanical strength loss. The addition of UV stabilizers and antioxidants is crucial to mitigating these effects and extending the lifespan of geotextile materials.
Aging Resistance Requirements
To ensure the long-term durability and maintain the functional properties of geotextiles, it is essential to incorporate high-performance UV stabilizers and antioxidants to combat sunlight exposure, moisture, and mechanical stress.
Recommended Additives for Geotextiles
- Polypropylene (PP): LS-770, LS-944, LS-119, LS-622, L-860 (masterbatch)
- Polyester (PET): LS-119, LS-622, UV-326, UV-328, UV-531
- Nylon (PA): LS-114, LS-944, LS-119, UV-234
Rainproof Cloth Application
Rainproof cloth, also known as tarpaulin or waterproof fabric, is primarily made from polypropylene (PP) and polyethylene (PE). It is widely used in storage facilities, construction sites, tents, military gear, industrial settings, docks, greenhouses, transportation (trucks, ships, and aircraft), and general outdoor covering applications. Given the extreme environmental conditions these materials endure—such as UV exposure, rain, temperature fluctuations, and mechanical stress—rainproof cloth must be engineered for enhanced durability and weather resistance.
Anti-Aging Requirements
To prevent UV-induced degradation, color fading, embrittlement, and mechanical weakening, rainproof cloth should be formulated with UV stabilizers and antioxidants that extend its service life and structural integrity.
Recommended Additives for Rainproof Cloth
- Anti-aging additives: LS-791, LS-944
Shade Net Application
Shade nets, also known as agricultural shade cloth, are lightweight, high-strength, and weather-resistant plastic mesh materials designed to protect crops, reduce heat stress, and improve growing conditions. These nets provide shading, cooling, wind protection, and pest control, replacing traditional organic mulching materials such as straw.
Shade nets are typically manufactured from high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). Due to their prolonged exposure to intense UV radiation, high temperatures, and varying environmental conditions, shade nets require advanced UV stabilization to maintain their performance and durability.
Anti-Aging Requirements
Shade nets must have a minimum outdoor lifespan of 3 years, while some applications require 5-10 years of durability. Laboratory UV aging tests can be conducted to validate product performance under simulated conditions.
Recommended Additives for Shade Nets
- Anti-aging additives: LS-944, LS-622, LS-119, LS-770
- Addition level: 0.3-0.8%
- Anti-aging masterbatch: L-650, L-691
- Addition level: 1-3%
