Product Overview
TAISOX® 7350M is an Ethylene-Vinyl Acetate Copolymer (EVA) produced by Formosa Plastics Corporation. This material has a Vinyl Acetate (VA) content of 18.0 wt% and belongs to the soft elastomer modified grade, featuring excellent flexibility and low-temperature impact resistance. Its core functional value lies in the combination of high ductility (800% elongation at break) and low melting temperature, making it suitable for industrial applications with specific requirements for sealing performance and weather resistance. This grade is specifically designed for extrusion, foaming, and hot-melt adhesive preparation processes.

Frequently Asked Questions (FAQs)
Q1: What are the recommended drying process parameters for TAISOX® 7350M before extrusion or foaming?
A1: EVA material has a certain degree of hygroscopicity. To prevent issues such as bubbles, surface silver streaks, or uneven foaming ratios during processing, it is recommended to dry the material before use. The recommended process is: long-term drying at a low temperature of 40–50°C (usually 2–4 hours) to avoid particle adhesion or pre-melting caused by excessive temperatures. The specific duration should be adjusted according to the humidity of the storage environment.
Q2: What are the differences in material selection between 7350M and other EVA grades with different VA contents (such as 7350F or 7360M)?
A2: 7350M has a VA content of 18.0 wt% and a melt flow index of 2.5 g/10min. Compared to grades with higher VA content, it has slightly higher rigidity and slightly lower transparency; compared to grades with lower VA content, it offers better flexibility and low-temperature performance. In foaming applications, 7350M has a moderate melt flow index, suitable for producing low-density closed-cell foam. If the application has extremely high requirements for adhesion (such as hot-melt adhesives), grades with higher VA content should be evaluated.
Q3: Is this material suitable for food-contact packaging or drinking water pipe fittings?
A3: The base resin of TAISOX® 7350M complies with FDA 21 CFR 177.1350 (Olefin Polymers) regarding food-contact materials. For specific food-contact applications (such as contact type, temperature, and duration) or drinking water pipe fittings (such as compliance with NSF/ANSI standards), it is recommended to request the corresponding Declaration of Compliance and third-party test reports to confirm that the material batch meets the sanitary permit requirements of specific regions.
