Touch-Feel & Anti-Scratch Additives for Consumer Electronics

TPE touch-feel and silicone masterbatch applications for consumer electronics products

In consumer electronics, the surface is the product: a phone case that feels silky, earbuds that don't turn sticky, a smartwatch strap that survives daily rubbing. Xiangxi's SV touch-feel modifiers, TPE-specific silicone masterbatches and anti-scratch agents give device housings, straps and overmolded grips a premium skin feel while keeping processing stable at scale.

Key Challenges in Consumer Electronics

Sticky, cheap-feeling surfaces — TPE/TPU parts turn tacky over time as low-molecular additives migrate and age.
Scratches and fingerprints — glossy housings show wear within weeks, hurting perceived quality.
Delamination in overmolding — soft-touch layers peel off rigid PC/ABS skeletons.
Thin-wall flow problems — miniaturized parts need better melt flow without losing mechanical strength.
Environmental compliance — global brands require RoHS, REACH and low-VOC materials.

1. SV Touch-Feel Modifier (Thermoplastic Silicone Vulcanizate)

Our SV / TP-SIV touch-feel modifier creates a stable, silky, skin-like surface on TPE and TPU parts. Because the siloxane phase is cured and cross-linked, it does not migrate — the surface stays smooth and non-sticky over the product's lifetime.

2. TPE-Specific Silicone Masterbatch

The TPE-specific silicone masterbatch improves dispersion and processing of TPE compounds for grips, straps and protective cases: better flow, finer surface, higher yield in overmolding.

3. Anti-Scratch Additives for Housings

For PC/ABS and PP housings, our anti-scratch system lowers surface friction and visible wear, keeping devices looking new — including phone frames, laptop shells and wearable housings.

Typical Applications

Product	Benefit
Phone cases and protective covers	Silk touch, anti-fingerprint staining, long-term non-sticky surface
Smartwatch bands and earbuds (TPE/TPU)	Skin-friendly feel, no tackiness with age, better color consistency
Overmolded grips and buttons	Strong hard-soft bonding, no delamination, clean parting lines
Laptop and tablet shells	Lower inner stress, anti-scratch finish, stable dimensions

FAQ — Consumer Electronics

Why do TPE phone cases turn sticky, and how do you prevent it?

Stickiness comes from low-molecular-weight plasticizers and oils migrating to the surface. Xiangxi's cured silicone systems (SV/TP-SIV) are non-migrating, so the surface stays smooth over time.

Can your additives improve hard-soft overmolding bonding?

Yes. Our overmolding and TPE-specific grades improve interfacial bonding between soft TPE layers and rigid PC/ABS, reducing delamination risk in drop tests.

Is the touch feel adjustable?

Yes. Dosage and grade control the surface from smooth-silky to soft-rubbery; we provide grading samples so you can select the exact feel for your product.
