Overview

TPV

TPV (Thermoplastic Vulcanizate) is a polymer alloy combining dynamically vulcanized EPDM rubber particles within a thermoplastic polypropylene (PP) matrix. This structure delivers the environmental durability of EPDM, including resistance to heat, UV, ozone, and chemicals, while enabling thermoplastic processing and full recyclability. TPV offers excellent elastic recovery, low compression set, and improved oil resistance compared to EPDM, making it well-suited for demanding industrial and marine environments.

Overview

Silicone

Silicone rubber is a high-performance inorganic polymer with a polysiloxane backbone, offering unmatched thermal stability from -100°C to +250°C. It is inherently resistant to UV and ozone, hydrophobic, and low in surface energy, which reduces biofouling and enables easy cleaning. While mechanically weaker than other elastomers, silicone excels in extreme environments and sensitive applications where chemical inertness and fouling resistance are critical.

Overview

PVC

Flexible PVC (Polyvinyl Chloride) hoses are valued for their low cost, corrosion resistance, and puncture-resistant properties. While standard PVC hoses can lose flexibility over time due to plasticizer migration, which also promotes biofilm growth and clogging, AeroFlux's PVC hoses use higher-molecular-weight PVC for slower plasticizer release, supporting reliable long-distance air distribution with improved operational longevity and reduced pollution.

Overview

NBR

NBR (Nitrile Butadiene Rubber) is a copolymer of acrylonitrile and butadiene, prized for its outstanding resistance to oils, fuels, and greases. It also offers good water resistance, making it suitable for specific industrial wastewater applications, such as food processing. However, NBR is sensitive to UV and ozone and can become brittle at low temperatures, limiting its use to protected or submerged environments rather than outdoor exposure.

PU

Polyether-based polyurethane (PU) offers exceptional mechanical performance, with superior abrasion, tear, and cut resistance that ensures long-lasting durability under demanding conditions. It maintains hydrolytic stability and can be formulated for UV, weather, and chemical resistance. AeroFlux’s advanced PU aeration hoses feature fouling-release surfaces that shed organisms, making them ideal for applications with high physical or environmental stress.

Overview

SIS

SIS (Styrene-Isoprene-Styrene) is a thermoplastic elastomer combining rubbery elasticity with thermoplastic processability. It offers high tack and adhesion, good strength, flexibility, and excellent aging resistance. Its unique stickiness allows long-length air transfer before apertures open, making it ideal for extra-long aeration hoses that ensure uniform air distribution over distances of 1000 to 2000m. SIS is also recyclable and eco-friendly.

SEBS

SEBS (Styrene-Ethylene-Butylene-Styrene) is a hydrogenated version of SBS, offering a chemically stable, saturated mid-block that delivers exceptional resistance to UV, ozone, weathering, and thermal degradation. It combines high elasticity, flexibility, and a soft, rubber-like feel with broad chemical resistance, biocompatibility, and eco-friendliness. SEBS is ideal for sensitive or sterilized water systems, including medical wastewater and specialty aquaculture applications.

Overview

SBS

SBS (Styrene-Butadiene-Styrene) is a thermoplastic elastomer offering rubber-like elasticity with excellent abrasion resistance, good low-temperature flexibility, and high tensile strength. It tolerates high pressures, making it suitable for deep water aeration and high-air-pressure systems. Economical and low-toxicity, SBS provides an eco-friendly alternative to PVC, though it is not recommended for surface-level exposure due to poor UV and ozone resistance.

Overview

EPDM

EPDM (Ethylene Propylene Diene Monomer) is the industry benchmark for outdoor and water-contact aeration applications, valued for its long-term stability and proven performance. Its chemically saturated polymer backbone delivers exceptional resistance to UV exposure, ozone, heat, and oxidation, while maintaining flexibility across a wide temperature range. AeroFlux’s EPDM hose is enhanced with copper oxide (CuO) filler to improve biofouling resistance, reducing microorganism buildup and minimizing clogging risks in continuous water immersion environments.
