What We Solve

Most Bonding Failures Are A Materials Mismatch Not A Machine Fault

Most bonding failures are a materials mismatch, not a machine fault: the melt range fights the press, the particle size blocks the screen, or the polymer will not wet the substrate. We select the grade around the process you already run.

01

Transfers Crack Or Peel After Washing

Elastic garments need a soft, high-elongation adhesive. A rigid powder holds on the press table and fails on the body. TPU powder keeps the stretch; PES holds the wash.

02

Powder Blocks The Screen Or Dusts The Line

Particle size decides whether powder passes the mesh cleanly. We cut PA and TPU powders into 0-80, 80-180, 100-300 and 200-500 micron fractions so the grade matches the mesh instead of the mesh matching the grade.

03

Potting Compounds Damage The Component

Two-part resins cure exothermically and shrink onto fragile parts. Low pressure moulding with polyamide resin encapsulates in 8 to 50 seconds with no chemical reaction and no cure stress.

04

Counters And Toe Puffs Delaminate

Shoe uppers face heat, moisture and flex at the same time. Polyamide and copolyester counter adhesives are built for that combination rather than for flat lamination.

05

One Grade Cannot Cover The Whole Product Range

Lamination, transfer printing, moulding and filter bonding pull the melt range in different directions. Carrying PA, TPU, PES and PO under one supplier removes the compromise grade.

06

Solvent Adhesives Fail The Customer Audit

Thermoplastic hot melts contain no solvent and are re-meltable, which removes the VOC question from apparel, footwear and automotive interior audits.

Why United Industry

One Supplier Across Every Polymer And Every Form

One supplier covering all four polymer families and all three forms, so a grade change does not mean a new vendor, a new audit and a new lead time.

01

Four Polymer Families Under One Roof

Polyamide, thermoplastic polyurethane, copolyester and polyolefin. You are not pushed toward the one chemistry a supplier happens to stock.

02

Three Forms Of The Same Chemistry

Granule for moulding and extrusion, powder for scatter coating and transfer printing, film for lamination and seamless bonding.

03

Grades Defined By Process Data

Melt range, viscosity, flow beginning temperature and particle size are published per grade, so the selection is made against your press settings.

04

Raw Material Supply As Well As Compounds

We supply resin raw material alongside finished adhesives, which matters if you compound or coat in house.

05

Customisation Is The Normal Case

Film thickness, roll width, roll length and powder fraction are cut to the order rather than sold from a fixed list.

06

Shanghai Base With Export Handling

Production and trade are handled by the same company in Jinshan District, Shanghai, so technical questions and shipping questions go to one place.

FAQ

Hot Melt Adhesive Questions We Are Asked Most

What types of hot melt adhesive do you supply

Thermoplastic hot melt adhesives based on polyamide, thermoplastic polyurethane, polyester and polyolefin, supplied as granule, powder and film.

Which industries use your products

Our hot melt adhesive products are widely used in heat transfer printing, shoe materials, low pressure injection moulding, filters, conveyor belts and automotive interiors.

How do I choose between polyamide TPU and polyester

Polyamide for bond strength and heat stability, TPU for elasticity and soft hand feel, polyester for wash resistance where elasticity is not required. Tell us which failure you are trying to avoid and the choice is usually immediate.

Do you supply raw material as well as finished adhesive

Yes. In addition to raw material supply we provide thermoplastic hot melt adhesives of polyamide, polyurethane, polyester and polyolefin.

Can products be customised

Yes. Particle fractions, film thickness, roll width and roll length are cut to the order, and other specifications can be customised on request.

How do I get a quotation

Email us with the grade or application, the form you need, the quantity and the destination port.

Tell Us The Substrates And The Temperature Limits

Three facts narrow the grade list faster than any data sheet: the two substrates, the service temperature and the process temperature your line can run. Send those and we will come back with a shortlist.
