CHAPTER 2 | PROCESS SETTINGS
Density Modified Formulations
Gravi-Tech™ polymer-metal composites are high-density materials developed as thermoplastic-
based alternatives to metals.
Solvent
Solvents soften surfaces of plastic (plastic
must be soluble)—best for amorphous or
low crystalline plastics, such as ABS, acrylic,
cellulosic, PC, PS, PPO, and vinyls.
Venting Guidelines by Resin
• PC: .001"–.002" depth & .250" width
• PC/PSU: .002"–.003" depth & .250" width
• PES: .003"–.004" depth & .250" width
• PEI: .001"–.003" depth & .250" width
• PP: .001"–.002" depth & .250" width
• ABS: .0015"–.0025" depth & .250" width
• PEEK: .002"–.004" depth & .250" width

HOW VERSAFLEX TPEs MAKE THE DIFFERENCE IN PORTABLE SPEAKERS APPLICATIONS
GASKETS
Water and Dust Protection
- Tight housing seals with no leakage over time
Reduced Manufacturing Costs
- Eliminates sourcing and assembly steps required of
O-rings by overmolding directly onto the substrate;
strong adhesion to PC & ABS
- Faster cycle times than silicone or TPU
Design Freedom
- Injection molding TPEs in gaskets enables
complex designs in which simple O-rings would be
challenging to assemble
SPEAKER SKINS
Durable Look and Feel
- Silky feel soft touch
- Long lasting aesthetics with abrasion and UV
resistance
Reduced Manufacturing Costs
- Eliminates sourcing and assembly steps
required of silicone skins by overmolding
directly onto the substrate; strong
adhesion to PC & ABS
- Faster cycle times than silicone or TPU
Design Freedom
- Overmolding TPE removes the need for
mechanical interlocks and primers to get
silicone materials to adhere to substrates

At first, they experimented with pre-colored
ABS, but the ABS parts failed the company’s
requirements for color retention after exposure
to UV light.
