TPU Hot Melt Adhesive Particles

TPU hot melt adhesive particles are granular hot melt adhesive materials made from thermoplastic polyurethane resin through specific processes.

It melts into a liquid state when heated, and can quickly solidify after cooling, thereby achieving adhesion to various materials. 

It is mainly composed of thermoplastic polyurethane resin, and may also add auxiliary components such as tackifiers, antioxidants, fillers, etc. to improve its performance and processing characteristics.

01  The Characteristics of TPU Hot Melt Adhesive Characteristics.

TPU hot melt adhesive has good performance, detailed introduction is as follows:

Excellent adhesion

Has excellent adhesive strength, can firmly bond various materials such as plastic, metal, wood, leather, fabric, etc., and the bonding effect is long-lasting, not easy to peel off.

Flexibility and elasticity

TPU is composed of soft and hard segments, which give it good flexibility and elasticity, and can adapt to the thermal expansion and contraction of different materials, ensuring that the bonding area remains stable under various deformation conditions.

Chemical corrosion resistance

It has good resistance to many common chemical substances, such as acid, alkali, oil, etc., is not easily corroded, and can ensure that the bonding site maintains stable performance in a chemical environment.

Water resistance and high/low temperature resistance

Has excellent water resistance and can maintain adhesive performance in humid environments; At the same time, it has good resistance to high and low temperatures and can be used in a wide temperature range to adapt to different environmental conditions.

Environmental Friendliness

Compared with traditional solvent based adhesives, TPU hot melt adhesive does not contain organic solvents, does not produce volatile organic compounds (VOCs), is harmless to the environment and human health, and meets environmental protection requirements.

02   The Application Fields of TPU Hot Melt Adhesive 

In daily life, there are many items that use hot melt adhesive for bonding, but what exactly is TPU hot melt adhesive? What other areas can it be used in?

Apparel Industry

It can be used for bonding waterproof zippers, pockets, labels, etc. Its water resistance and chemical corrosion resistance can ensure that clothing will not peel during washing and wearing, and its softness and elasticity will not affect the comfort and appearance of the clothing.

Footwear Industry

Widely used in the bonding of shoe soles and uppers, it can quickly cure, improve production efficiency, ensure the firmness and durability of the bonding area, and its flexibility and elasticity make shoes more comfortable to wear, reducing foot fatigue.

Automotive Industry

It can be used for bonding automotive interior parts, such as instrument panels, seats, door panels, etc. Its high and low temperature resistance and chemical corrosion resistance can adapt to the complex environment inside the car, ensuring the firmness and durability of the interior parts.

Electronic Product Industry

It can be used for shell bonding, screen bonding, etc. of devices such as mobile phones, tablets, laptops, etc. Its bonding strength is high and flexibility is good, which can protect electronic products from external impact and vibration during use. At the same time, its insulation performance can also ensure the safety performance of electronic products.

Other Fields

It can also be used in reflective materials, filter materials, home decoration, medical and health fields, such as supplying different materials of base glue and laminating layers for the reflective material industry, and bonding invisible car wrap films.

Hot Melt Adhesive Film

As the name suggests, hot melt adhesive film is a type of film product that can quickly adhere two layers of woven fabric or other materials. It is widely used in textile products, mainly in the form of mesh, and there are also ordinary films. The main purpose of using hot melt adhesive film in the textile industry is to replace sewing with sticking, which can quickly produce related products at a speed 2-10 times faster than sewing. In addition, TPU hot melt adhesive film has the characteristics of low temperature resistance and easy processing, and is also very suitable for making fire hoses.

Water Stop Rubber Strip

Also known as heat sealing tape, it is heated and pressed onto the sewing joints of waterproof shoes and camping tents using a hot air seam sealing machine or high-frequency heat sealing machine. By bonding the waterproof adhesive strip to the sewing connection of the product, it can mainly achieve the effects of preventing water leakage, air leakage, and bacteria. Widely used in various textile products, such as the folding of collars and cuffs of clothes or the bonding of various textile fabrics, it can maintain good elasticity, stickiness, waterproofness, and flexibility in any environment.
