EVA foam tape is a new type of environmentally friendly plastic foam material, which has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and is non-toxic and non-absorbent. EVA rubber and plastic products are designed to be processed and formed, and their shockproof performance is better than traditional foam materials such as polystyrene (foam), and it meets environmental protection requirements. It is the best choice for export products. Compared with shock-proof packaging, it can be cut and formed; due to the large difference in density, it can also have a wider range of uses. EVA foam tape has good softness and rubber-like elasticity. It can still have good flexibility and transparency and surface gloss at -50°C. Good chemical stability, good aging resistance, and ozone resistance. Non-toxic. Good blending with fillers, good coloring, and molding processability.
It has a great relationship with vinyl acetate content, molecular weight, and melts index. When the melt index (MI) is constant and the content of vinyl acetate (VAC) increases, its elasticity, flexibility, compatibility, and transparency will also increase. When the VAC content is reduced, the performance is close to that of polyethylene, the rigidity is increased, and the wear resistance and electrical insulation are improved. If the VAC content is constant and the melt index increases, the softening point will decrease, and the processability and surface gloss will improve but the strength will decrease. Otherwise, with the decrease of MI, the molecular weight will increase, and impact performance and environmental stress crack resistance will increase.
