To produce a glossy finish, a polished mold is required and an unfilled grade should be used.
A highly polished tool and a transparent material are required to produce a part with good clarity.
If a matte finish is required, a rougher mold texture should be used (or a GLS product such as GLS Versalloy™ TPV Alloys, which naturally produce a matte surface).

Drying is not typically required for GLS TPEs.
Slower fill rates may be required if surface flow defects occur.
This process is used when highly accurate molding tolerances are required.

For starters, the insert was made from thermoset silicone rubber – a tried-and-true material that requires a slow-and-costly manufacturing process.
Extensive compatibility testing confirmed that the new grades would bond chemically with the engineering thermoplastic rigid substrate required in the device.
Finally, the new TPE grades also boasted lower extractables because they required no crosslinking, unlike thermoset silicones.

Avient includes in its Code of Conduct and Supplier Code of Conduct internal accountability standards related to slavery and human trafficking to which all employees, agents and consultants are required to adhere.
Where required by law, we also have specific disclosures and processes in place, including a supplier audit program that focuses on human trafficking.
Last year, Avient completed the first phase of the program which focused on training and evaluating our suppliers on environmental, social, and governance requirements, per the UN Global Compact principles.

If a reinforced substrate material is used a high hardness abrasion resistant steel may be required.
A polished mold is required to produce a glossy or good clarity surface.
Requires floater plate

The teams evaluated the existing materials and found that the required blending and drying processes had created inefficiencies.
Working together, they identified an alternative material that met the performance requirements of the product but did not require blending.

Using Trilliant XR can also contribute to overall system cost reduction by avoiding costly record management and reporting requirements of using lead.
Customizable density to specific gravity requirements, or matching the density of lead (11gm/cm3)

And unlike silicone and other denesting agents, Cesa Denesting additives don’t require extra steps in the manufacturing process, maintain the transparency of the sheet, and allow for metallization and printing of the packaging.
Complies with FDA packaging requirements

This reduces the number of required prototypes before shifting into the production mold.
As with all engineering and design, quality results from engineering simulation require the right capabilities, expertise, and experience.
