Provide a 0.003" to 0.005" (0.076 mm to 0.127 mm) interference when using plastic inserts or substrates, to take into account shrinkage, sinks and tolerances.

Choose the material with the lower cost; this cost is essentially on a lbs-volume basis and is used throughout the rubber and plastic industry.

BIO-BASED SOLUTIONS
Bio-polymers are already used with success in
different plastic products, notably in packaging,
but to be used in healthcare applications, they
need to be risk-assessed.
REDUCED MATERIAL USE
Chemical Foaming Agents (CFA)
Mevopur CFA products are the result of Avient’s
combined experiences in the development
of chemical foaming agents for automotive
plastic components and of polymer solutions
for healthcare applications.
They
also improve the visual appearance of plastic
components by reducing sink marks.

In fact,
you may have found yourself swimming in plastics alphabet soup and unsure
where to start.
Thermoplastic elastomers (TPEs) are a type of plastic that have been
refined to create a soft, rubbery feel—and they’re everywhere.
Most thermoplastic
elastomer products are also recyclable
under Plastic Recycling Code 7.

TPE chemistry and the type of engineering plastic play a critical role in influencing wettability.
We have modified ASTM D903 method for plastics to evaluate the adhesion of soft TPE onto rigid
thermoplastic.
Many consumers prefer a “warm” soft touch feel over a hard plastic feel.
