Bonding Urethane To Metal, PVC And Nylon

Our manufacturing expertise includes bonding polyurethane to metal and steel for a wide range of industries over our decades in business. Over the last 20 years, our customers started requesting that we bond polyurethane to pvc and nylon. Not only did we not shy away from the challenge, but we have been successful and our customers are very happy.

Process Of Bonding Urethane

Preparing a core for the bonding process can vary depending on a few things. What type of material the core is made of, is the core clean and new, or does the core need to be stripped of old material. If we are recovering a core, we will first clean the core of all existing material, oil and rust.

No matter what surface we are bonding to, it has to be scuffed up to improve the bond between the core material and the polyurethane. This is a necessary process for the urethane to have an unbreakable bond with the substrate. The primary methods we use to achieve the perfect bonding surface is either sanding or by grit blasting.

The cores are then cleaned of any residue and coated with a bonding agent. For the bond to adhere properly to the core/insert, we place them in a high heat oven and bake it on. We then start the process of molding the polyurethane onto the core.

Benefits Of Bonding Polyurethane To A Substrate

Non-Scratching - Metal on its own can damage a product by scratching/gauging it, while bonded urethane on the other hand will not.
Non-Marring - If you have metal encased in rubber, it will leave black marks on the product it comes into contact with, however urethane does not mar/mark.
Abrasion Resistance - Metal can be coated to help reduce abrasion and friction, however metal will eventually wear out. Urethane can be formulated to your specific abrasion resistance needs. If friction is an issue, we are able to reduce it with additives such as molly or graphite.
Strength - Urethane is an elastomer, which means it is resilient and non-brittle.
Weight and Cost - PVC and nylon are both lite weight, less expensive than metal, and can be used as your core to apply bonded urethane to.
