What is TPE adhesive?

TPE adhesive, as the name implies, is to glue TPE soft adhesive material onto other materials. The processing methods generally used are two-color injection molding machine, or the general injection molding machine, the use of plastic mold, two injection molding. The commonly used TPE material refers to TPE-S, namely polystyrene thermoplastic elastomer, which is a thermoplastic engineering plastic obtained by composite modification of SEBS or SBS elastomer as the base material. Tpe-s elastomers are also known as TPE or TPR in the elastomer industry.

Advantages of TPE adhesive

1, the general thermoplastic molding machine processing, do not need special processing equipment.

2, easy to recycle, reduce costs. The waste generated in the production process (escape of raw edges, extruded waste glue) and the final waste can be directly returned for reuse; The used TPE products can be simply regenerated and recycled to reduce environmental pollution and expand renewable resources.

3. The processing method is the same as that of conventional plastics, injection molding and extrusion are common molding methods.

4, TPE soft adhesive is modified material, through the adjustment of the formula, can have different hardness and physical properties.

5, TPE material has excellent soft touch and non-slip, and good elastic touch, applied in the secondary injection molding, can be with PP, ABS, PA, PC and so on hard plastic bag adhesive, has good adhesion, often used in daily use products, sports and fitness products, hardware tool products handle accessories, can be the holding of the products.

6, wear resistance, scratch resistance, aging resistance, chemical resistance, electrical insulation, UV resistance, weather resistance, acid and alkali resistance, low temperature resistance, anti-slip, anti-seismic.

7, combustion will not produce harmful substances, repeated use, water mouth material scraps can be recycled.

8, broad hardness design space, easy to color, beautiful products, colorful colors!

9, the material is environmentally friendly and non-toxic, can provide environmental testing report.

10. TPE materials are processed by coating, spraying and bonding, and commonly used products such as handles, handles and electronic materials. The material gives the product a comfortable touch, improves the grip, improves the beauty of the product and the added value of the product.

TPE plastic injection need attention:

One of the most important applications of thermoplastic elastomers -- coated hard cemented components. Plastic packaging secondary injection molding process should pay attention to:

1. The compatibility of TPE and hard cemented components should be matched, and the molecular solubility should be close, so that the molecular compatibility is better.

2. Sharp corners should be avoided as far as possible in the design to ensure good contact between TPE and hard adhesive parts and improve the bonding effect.

3, through the appropriate exhaust to avoid the mold cavity left gas.

4. Balance the thickness of the TPE with the desired tactile sensation.

5. Keep the TPE melting temperature to ensure the bonding effect.

6, TPE material coating molding needs to be baked and reprocessed to reduce the surface of the product water lines, to achieve uniform surface color effect.

7, the choice of color masterbatch, its carrier resin and TPE and structural materials are compatible.

8, for smooth surface to special treatment, the purpose is to increase the soft adhesive and hard adhesive bonding contact surface, strengthen the bonding effect.

9. Flow length/product thickness ratio of TPE is less than 150:1.

10, TPE should have a good flow, because TPE coating thickness and size ratio is small, TPE usually needs to flow through a longer path and thin wall area to fill the mold.

11. Use a good adhesive

TPE coating material application field

1. Everyday items

Handles (knives, combs, scissors, suitcases, toothbrush handles), bag handles, cutlery handles, foot MATS (for inside and outside), table MATS, and other rubber products.

2. Tool materials

Tool handle (screwdriver, hammer, saw, power tool, drill, etc.)

3. Game product parts

Steering wheel, handle, mouse cover, liner, shell cover, soft, shock-proof parts.

4. Sports equipment

Handlebars (golf balls, rackets, bicycles, ski equipment, water skiing equipment, etc.), diving equipment (frog shoes, frog goggles, breathing tube, flashlight, etc.), sports pads, bicycle grips

5. Consumer electronics

Common consumer electronics products applied to TPE coated PC include mobile phone protective case, tablet computer protective case, smart wristwatch, electric toothbrush handle and so on. It provides a soft, comfortable feel, non-slip resistance and even durability.

6. Automobile manufacturing

TPE adhesive PC has strong resistance, high hardness and good temperature resistance. In this industry, the demand for plastic PC will be more and more large.

7. Medical devices

The physical and chemical properties of PC are very stable, so it is widely used in some medical equipment that needs frequent disinfection, such as syringes, masks and so on.

8. Building materials industry

It is made of polycarbonate, which has excellent resistance, radiation resistance and light transmission. The advantages of encapsulation are overwhelming. This makes it in the building materials industry has a good application advantage.

9. Lenses

Generally through the injection molding technology to achieve the encapsulation, usually do small lenses are relatively simple, small lenses are mainly used in the clamshell of the phone. There are two injection injection designs, and then through the mold, you can form a molded small lens.
