A good geomembrane masterbatch grade will have excellent long-term use, good dispersion and afford very good UV protection. Our range of high-performance masterbatches, specially designed for use in applications such as potable water containment, landfill containment and waterproof tunnel lining, can extend the life of geomembranes produced from a wide range of polymers. They provide very good dispersion and conform with internationally recognized standards. The high-quality carbon black that we use provides superior UV performance, while our advanced stabilization package provides excellent long-term thermal stability and life prediction.

HIGHLIGHTS

Durability

The right selection anti-oxidations and UV additives is critical to maintaining the mechanical properties of geosynthetics. We have extensive expertise on additive packages and their incorporation into polymers to produce highly technical solutions for geosynthetics, so our additive solutions meet and exceed international standards on weathering and ageing giving regulators and engineers confidence in the durability and long-term integrity of geosynthetic lining systems.

Chemical resistance

The ultimate durability of a geosynthetic compounds used in municipal solid waste landfill, bunding and chemical separation, is a function of the stress cracking resistance, the effectiveness of its antioxidation additives, the stresses generated in the geosynthetic applications during installation operation, and the stress relaxation rate. With our extensive knowledge of polymers and additives, we develop the correct solutions for geosynthetic applications where chemical resistance is required.

Weldability

Ensuring good weldability, by eliminating the migration of additives that can cause fusion welding problems, requires careful selection of the correct masterbatch carrier system and additive package. We have the extensive knowledge, expertise and testing to ensure that all critical parameters are met.

Superior mechanical properties

Regardless of the polymer being used, our compounds and masterbatches can be formulated to provide the optimal balance of mechanical properties, including environmental stress cracking, tensile strength, flexural strength, impact, hardness, creep resistance, heat deflection temperature, hysteresis and thermal mechanical performance, to give you the widest choice of materials suitable for your application.

Our Products

High UV

Polymers are susceptible to photo-oxidation that results in the deterioration of mechanical properties and surface appearance over time. This is especially critical for pipes and fittings which remain above ground for a significant amount of time. Our range of masterbatches eliminate or vastly reduce the effects of UV radiation and photo-oxidation.
