How to choose between HDPE, LDPE, EVA, and ECB based on chemical exposure and temperature ranges.
Read GuideA: Our products are manufactured using virgin polymer resins (HDPE, LDPE, EVA) integrated with advanced UV stabilizers and anti-aging additives. This ensures high tensile strength, chemical inertness, and a prolonged operational lifespan exceeding 25 years in extreme soil and aquatic environments.
A: Yes. Backed by our dedicated chemical and mechanical engineering teams, we offer full customization of thickness, texture (smooth or textured surfaces), color (including double-color liners for leak detection), and roll dimensions to meet exact international engineering standards.
A: All our production facilities operate under strict adherence to ISO9001 (Quality Management), ISO14001 (Environmental Management), and OHSAS18001 (Occupational Health and Safety) standards, accompanied by rigorous third-party laboratory testing reports for every batch.
