Characteristics and Applications of Foam Tape Substrate for Automotive Use

Foam tape substrates for automotive applications include several types such as IXPE foam, XPE foam, high-density PE foam, EVA foam, and acrylic foam. Among them, IXPE foam tape is the most widely used. It is made of white or black foam as the substrate, with red, green, or blue PE release film for separation.

Composition of IXPE Foam Tape:

1. Tape substrate: IXPE foam is used as the base material, with a thickness as thin as 0.1mm (thinner than ordinary A4 paper), commonly available in thicknesses of 1mm, 2mm, etc. The density is mainly 20 times the expansion.

2. IXPE foam tape can be attached with centrifugal film, release paper, etc.

3. Tape adhesive: It can be single-sided adhesive or double-sided adhesive, with different types of adhesives such as oil-based adhesive, water-based adhesive, hot melt adhesive, and acrylic adhesive.

Performance Characteristics of IXPE Foam Tape Substrate:

IXPE, also known as cross-linked polyethylene foam, features a smooth surface, closed-cell foam structure, and uniform and fine pores, with stable physical properties. The specific characteristics are as follows:

Insulation: The closed-cell structure of IXPE foam tape substrate prevents energy exchange caused by air convection. IXPE foam materials are commonly used for making insulation pipes, insulation boards, etc. due to their excellent thermal insulation performance. Moreover, IXPE materials also have anti-condensation properties, making them widely used in insulation and heat insulation in damp environments such as refrigerators, air conditioners, and cold storage. Therefore, IXPE foam is very suitable as the substrate for automotive foam tape.

Cushioning: IXPE foam belongs to semi-rigid foam and has good cushioning properties, allowing it to absorb strong impacts without losing its original shape. It has been widely used in the packaging of precision instruments, semiconductors, electronic products, etc. As the substrate for automotive foam tape, IXPE foam provides certain collision protection and cushioning functions.

Sound insulation: IXPE foam materials have sound insulation and noise reduction capabilities, making them suitable for sound insulation materials in environments with strong noise from automobiles, electric motors, engines, etc.

Easy formability: IXPE has strong heat resistance, good extensibility, uniform density, and can be vacuum-formed and thermally formed into deep shapes. Therefore, it can be used in materials for automotive air conditioning evaporators, hot-pressed roofs, interior parts, shoe materials, etc.

Other properties: In addition, IXPE foam materials are non-toxic, odorless, resistant to chemicals, oil, acid, salt, and various other chemical substances. They are easy to process and can be easily cut to the desired shape. IXPE can also adhere to various materials, making it an efficient, energy-saving, and environmentally friendly material. It is precisely because of these characteristics that IXPE foam has become the preferred choice for the substrate of automotive foam tape.

Characteristics and Applications of Automotive Foam Tape:

Automotive foam tape has strong adhesion, good weather resistance, waterproofness, solvent resistance, aging resistance, and elasticity of the foam substrate, providing excellent adhesion to uneven surfaces.

It is widely used in automotive interior parts, door trims, rain visors, signboard adhesion and fixation, etc. It has strong adhesion, good shock absorption, and strong weather resistance. It is used for bonding between car and motorcycle emblems, household appliances, engineering decoration, structural bonding and fixation of curtain walls.

It is used for bonding and fixation of automotive decorative strips, automotive glass, car pedals, seals, splashboards, wheel arches, flow deflectors, brake lights on license plates, and interior boards. PE foam tape is made of PE foam as the substrate, with high-performance oil-based acrylic adhesive coated on both sides. With an elastic foam substrate, it has strong adhesion, excellent weather resistance, waterproofness, solvent resistance, and aging resistance, providing excellent adhesion to uneven surfaces. It is suitable for the electronics industry, furniture industry, metal, automotive interior and exterior decoration, signs, nameplates, accessories, and other fields.
