Isobutylene-Isoprene Rubber (Butyl) — Low-permeability rubber used where air/gas retention and damping matter, including some sealing bladders.
Screening hints only. Certifications (medical, food-contact, flame, HazLoc) apply to specific grades and finished equipment — verify with supplier documentation.
Qualitative screening for gaskets, O-rings, soft goods, and rubber buttons — not datasheet values. Compounds and mold textures vary widely within each family.
Shore A ~50–60
Often soft-to-medium; the standout trait is low rebound / damping, not springiness.
Shore A bands and texture notes are educational screening aids for buttons, keypads, and soft-touch parts — not datasheet values or mold-texture guarantees. Always specify hardness, finish, and texture on the drawing/compound sheet.
Gel-like remote keys, ultra-soft mute buttons
TV remotes, soft-touch power keys, thumb grips
Appliance panels, calculator-style keys, light industrial HMI
Firmer keypad stops, many gaskets, durable button skirts
Feet, hard bumpers, stiff button surrounds
Near-rigid rubber parts; less “squishy button” feel
Clean consumer look; hides fingerprints better than gloss.
Premium sheen; shows fingerprints and micro-scratches more.
Velvety or rubberized feel for premium button tops and grips.
Subtle grain improves finger purchase without looking industrial.
Aggressive grip for tools/outdoor UIs; can feel rough.
Directional cues for sliders or long press zones.
Tactile target for small keys; common on remotes.
Soft diffuse texture that hides tooling marks on larger pads.
Melt resin pellets and inject into a closed mold to produce repeatable parts.
