Adchem Introduces 4377M & 4380M Adhesive Tapes

Hybrid Tapes Combine the Benefits of Rubber and Acrylic Adhesive Technologies

Adchem Corporation, a leading manufacturer of innovative pressure-sensitive adhesive tape systems, has expanded its foam bonding solutions with the introduction of its 4377M and 4380M adhesive tapes. Adchem specializes in providing custom foam bonding solutions for a wide variety of industries, such as automotive, electronics, construction, graphic arts, medical, and general industrial. The most recent additions to their 4300 Series adhesive tapes, the multipurpose 4377M and 4380M, were originally designed for the automotive industry, and are ideal for demanding foam bonding applications with stringent insulation and sound reduction requirements.

Adchem's 4377M is designed with a high tack, high peel, moderate shear rubber-based adhesive coating on the liner side and a high-tack, low shear acrylic adhesive coating on the exposed side, and a 0.5 mil polyester film carrier to facilitate die cutting. The adhesive coating has an exposed side of 1.3 mils and a liner side of 1.4 mils. The 12-pt natural polycoated kraft liner is well suited for kiss cutting. Similar in design, the higher caliper exposed side of 4380M provides improved temperature resistance. Additionally, both the 4377M and 4380M have been engineered to meet the requirements of industry standard automotive specifications.

The unique design of these products allows the exposed side of the adhesive to bond to more than 30 popular foam materials, including urethanes, epichlorohydrins, and EPDM blends. The liner side of the adhesive provides superior bonding properties to surfaces such as talc-filled polypropylene, mica-filled polypropylene, and mineral-filled nylons.

The leader in the foam fabrication market for more than 40 years, Adchem provides more than 50 unique adhesive solutions for customers' most demanding foam bonding needs. Its broad range of products reduces the need for large inventories of narrower spectrum systems. Adchem also offers competitive pricing and engineering support that are unmatched by both smaller and larger adhesive tape suppliers.
