Production status of foam tape raw materials

by:CROWN     2021-10-07

The tape industry has developed rapidly, and tape raw materials have also changed from natural products to products that can be made.

In recent years, the output of synthetic rubber and natural rubber has been increasing, especially the varieties of synthetic rubber. The original tape raw materials rely on imported elastic materials such as SIS and SBS.

Regardless of variety or quantity, it can meet the needs of the pressure-sensitive adhesive tape industry. In the past, only rosin and terpene resins were provided, but now a variety of petroleum resins and hydrogenated petroleum resins are available.

Many tape raw materials can be produced by domestic manufacturers, which will further develop the tape industry.

Acrylic foam tape is based on EVA or PE foam, coated with solvent-based (or hot-melt) pressure-sensitive adhesive on one or both sides, and then coated with release paper. The foam tape has the function of sealing and shock absorption.

Foam tape is the current fully automatic continuous coating line, using PU, PE, EVA, XPE, EPDM, rubber, and needle felt, hot melt felt, and other foam as the basic material. Use various high-quality auxiliary materials to coat various high-quality domestic and imported self-adhesives. Foam tape is a soft, heat-insulating, heat-preserving, and sealing tape compounded by a special process.

Foam tape is widely used in air conditioning and refrigeration and interior decoration of locomotives and ships; air duct interfaces and dampers of automobile air conditioners and civil air conditioners; what are the characteristics of foam tapes such as cement joints in urban buildings, sealing of doors and windows, and heat insulation? ? It has the characteristics of firm bonding, fast and convenient use, and is a product with excellent performance such as sound insulation, heat insulation, shadow resistance, waterproof (closed cell), shock absorption, sealing environmental protection, and sound absorption.

Acrylic foam double-sided tape refers to a double-sided tape formed by coating acrylic adhesive on both sides of an acrylic foam substrate. The colors are white, gray, transparent, and black, and the thickness is also large, mainly 0.25mm, 0.4mm, 0.5mm, 0.64mm, 0.8mm, 1.2mm, 1.6mm, 2.0mm, 3.0mm, and the release type has white separation. The typed paper and red release film have the advantages of high adhesion, high retention, water-resistance, temperature resistance, and strong load-bearing capacity. They are the best among all forms. They can be used for scratch-resistant strips, pedals, and umbrellas. Bonding and fixing of plates, sealing strips, anti-collision strips, rear fenders, nameplate decoration strips, door peripheral protection strips, glass curtain walls, metal products, etc., applicable temperature: -20℃-120℃.
