Overmolding Techniques & Adhesion Requirements

SILIKE Si-TPVs Overmolding can adhere to other materials through injection molding. suitable for insert molding and or multiple material molding. Multiple material molding is otherwise known as Multi-shot injection molding, Two-Shot Molding, or 2K molding.

SI-TPVs have excellent adhesion to a variety of thermoplastics, from polypropylene and polyethylene to all kinds of engineering plastics.

When selecting an Si-TPV for an over-molding application, the substrate type should be considered. Not all Si-TPVs will bond to all types of substrates.

For more information regarding specific over-molding Si-TPVs and their corresponding substrate materials, please feel contact us.

Application

Si-TPV modified soft slip TPU is an innovative solution for the medical industry for applications such as thermometer overmolding, medical rollers, medical film surgical tablecloths, medical gloves and more. You can't go wrong with Si-TPV!

Thermoplastic elastomers vs. traditional materials in the medical industry

PVC

The medical device industry is gradually abandoning the use of PVC, mainly because they generally contain phthalate plasticizers, which can cause harm to humans and the environment when incinerated and disposed of by generating dioxins and other substances. While phthalate-free PVC compounds are now available for use in the medical industry, the life cycle of PVC itself is still an issue, leading manufacturers to prefer other alternative materials.

Latex

The problem with latex is the potential for users to be allergic to proteins, as well as industry concerns about the curable and leachable content and odor of the latex itself. Another factor is economics: processing rubber is more labor-intensive than processing Si-TPV materials, and the processing waste from Si-TPV products is recyclable.

Silicone Rubber

Often, many products that use silicone rubber do not need its high heat resistance or low compression set at high temperatures. Silicones certainly have their advantages, including the ability to withstand multiple sterilization cycles, but for some products, Si-TPV materials are a more cost-effective alternative. In many cases, they offer improvements over silicone. Typical applications where Si-TPV materials can be used in place of silicone are drains, bags, pump hoses, mask gaskets, seals, etc.
