Outstanding Mechanical Resilience and Elongation at Break: An elongation at break of up to 800% endows the material with exceptional tensile stretchability, tear resistance, and superior dynamic resilience.
Exceptional Low-Temperature Toughness: A brittleness temperature below -70 °C allows the product to maintain stable impact and bending resistance even in extremely cold or severe low-temperature environments.
Superior Processing Flowability and Foaming Adaptability: The melt flow rate (MI = 2.5) is scientifically designed to balance melt strength and flow uniformity, making it highly suitable for compression molding, injection molding, and extrusion processes.
Perfect Balance of Hardness and Flexibility: The combination of a Shore A hardness of 88 and a Shore D hardness of 38 provides necessary structural rigidity while maintaining a comfortable touch and softness.
Good Filler and Blending Compatibility: The base resin exhibits excellent compatibility with calcium carbonate, color masterbatches, and various rubber/plastic additives, supporting efficient compound pelletizing and color matching.
Footwear Industry & Athletic Equipment: Widely used in midsoles, insoles, athletic protection gear, and cushioning/shock-absorbing components for high-end athletic and casual shoes.
Cushioning Packaging & Consumer Electronics Accessories: Suitable for precision instrument shock-absorbing pads, electronics packaging inner liners, soft luggage structural parts, and various toy accessories.
Automotive Parts & Sealing Foams: Can be used to manufacture automotive interior damping pads, sealing strip foam substrates, wire and cable jackets, and automotive non-structural elastic components.
Daily Commodities & Sheet Extrusion: Utilized for producing multi-layer composite films, elastic hoses, daily anti-slip mats, yoga mats, and various high-elasticity foam sheets.
Q1: Does Formosa Plastics TAISOX® 7350M require drying before processing? What are the recommended process parameters?
A: Because virgin EVA resin exhibits very low moisture absorption under normal conditions, forced drying is typically unnecessary under standard injection molding or extrusion operations. However, if the raw material has been exposed to high humidity environments for an extended period or stored for a long time, short-term pre-drying at 50–60 °C for 2–3 hours is recommended to completely eliminate surface bubbles or flaws caused by trace moisture.
Q2: What are the core advantages of EVA 7350M compared to general polyethylene (PE) or standard thermoplastic elastomers (TPE)?
A: Compared to standard PE, TAISOX® 7350M incorporates 18% vinyl acetate (VA) components, significantly enhancing the material’s flexibility, elongation at break (up to 800%), and low-temperature impact resistance. Compared to higher-cost TPE/TPU elastomers, 7350M delivers excellent elasticity and tactile feel while offering higher cost-effectiveness, more mature processing technologies, and outstanding foam moldability.
Q3: Does this grade comply with global mainstream environmental and compliance certification standards?
A: Yes. TAISOX® 7350M manufactured by Formosa Plastics strictly complies with international environmental regulations, meeting the requirements of the EU RoHS directive and the REACH regulation concerning Substances of Very High Concern (SVHC). For specific import/export trade, food contact, or medical-assisted packaging applications, buyers can request the TDS, SDS, COA quality certificates, and environmental compliance declarations issued by the original manufacturer.
