Rubber & Polyurethane Products
Bili’s partner supplies custom rubber and polyurethane products for industrial, commercial, and specialty use. One of our flagship offerings is the flat-free tire, engineered using a proprietary micro-cellular polyurethane foam process that delivers outstanding durability, cushioning, and chemical resistance.
Flat-Free Polyurethane Tires – Puncture-Proof, Long-Life Industrial Tires
These tires are made from solid micro-cellular polyurethane foam, produced by combining polyol and isocyanate with a specialized reactive agent. This blend triggers a polymerization process, forming a dense yet elastic structure. The tires are cast using centrifugal molding machines that spin the molds at controlled speeds — creating a tough, seamless outer skin that’s up to twice as strong as traditional rubber.
Key features:
- Flat-free and puncture-resistant
- Non-marking and abrasion-resistant
- Chemical resistance to oils, solvents, and harsh cleaners
- Lightweight and shock-absorbing, with a natural bounce
The internal sponge-like foam contains millions of microscopic air pockets, mimicking the comfort of pneumatic tires while eliminating the risk of deflation or damage from debris.
These tires are ideal for:
- Warehouse carts and trolleys
- Industrial equipment
- Mobility aids and hospital carts
- Outdoor terrain vehicles where puncture resistance is essential
Custom Rubber Product Capabilities
In addition to tires, Bili partners also manufactures a wide range of rubber products, including:
- Rubber Sheets – EPDM, NBR, silicone, and natural rubber sheets in various thicknesses and hardness levels
- Gaskets & Seals – Die-cut or molded to shape, available in food-grade, oil-resistant, or high-temperature materials
- PU Components – Polyurethane bushings, bumpers, rollers, and custom-molded parts
- Injection-Molded Rubber Parts – For vibration control, sealing, or protective use across mechanical and electrical systems
All parts are manufactured to international standards and tolerances, with optional in-house QC inspections, CAD support, and technical validation.
