Skin-Friendly Platinum Silicone for SFX, Prosthetics and Skin Replication
CHT True Skin 30 is a 2-component, addition-curing (platinum-cure) liquid silicone elastomer with a Shore A 30 hardness, specially developed for skin replication, prosthetics and special effects. CHT has had the material tested for skin contact to ISO 10993-5 and ISO 10993-10. It combines extreme stretch (1000%), a translucent colour for easy pigmentation and a wide service temperature range of -55°C to +204°C. Easy 1:1 mix ratio, cures at room temperature or faster with heat.
Key Benefits
- Tested for skin contact: no cytotoxic effect (ISO 10993-5), no significant irritation and no sensitisation (ISO 10993-10)
- Extreme stretch: 1000% elongation at break (ISO 37) for realistic skin movement and durable prosthetics
- Translucent for perfect pigmentation: Clear base for accurate skin tones and colour mixing in SFX and body casting
- Wide service temperature: Stable from -55°C to +204°C
- Minimal shrinkage: <0.1% linear shrinkage for dimensionally accurate moulds and prosthetics
- Adjustable cure speed: 20 minutes pot life at 23°C, can be accelerated with heat for efficient production
Skin contact: what CHT has had tested
CHT has had True Skin 30 tested at Pacific BioLabs, focused on contact with the skin.
- ✓ ISO 10993-5:2009, cytotoxicity: the material is not considered to have a cytotoxic effect.
- ✓ ISO 10993-10:2010, irritation and sensitisation: intracutaneous reactivity and the maximisation test for delayed-type hypersensitivity. No biologically significant irritation and no sensitisation reactions, in saline as well as in cottonseed oil.
- ✓ FDA 21 CFR 177.2600: compliance with the US regulation for rubber articles intended for repeated food contact. This is a composition requirement, not a skin test.
- ✓ A REACH SVHC statement and a RoHS 3 statement are available.
The underlying CHT test reports and statements are available on request via info@siliconesandmore.com. To compare with other skin-friendly silicones and see exactly what each manufacturer claims, visit the category Skin-friendly and biocompatible silicones.
⚠️ What these tests do and do not say
- ✓ Tested for skin contact, not for mucosal contact. For mucosal contact up to 24 hours, Zhermack ZA SFX 0020 and ZA SFX 10 WT 10 are the documented choice.
- ✓ The tests apply to the pure, fully cured material. Pigment, softener, release agent, mix ratio and cure all affect the result of your piece.
- ✓ This is not a certification of your finished product. If you are making a medical device or a product with prolonged body contact, have the cured finished product tested by an accredited laboratory.
Typical Applications
- Special effects (SFX) and animatronics: realistic skin textures for film, TV and theatre
- Prosthetics and medical simulation: anatomically correct models and training phantoms
- Body casting and skin replication for artists
- Masks and cosplay with high detail reproduction
- Robotics and animatronics where a flexible, skin-like covering is required
Processing instructions:
- Stir both components A and B thoroughly before use (fillers may settle)
- Mix A and B at 1:1 by weight in a clean container (3 times the volume)
- Mix until the colour is uniform
- Degassing recommended: 30-50 mbar intermittently, 5-10 minutes
- Pour by gravity or pressure injection within the 20-minute pot life
- Allow to cure for 6-8 hours at 23°C, or accelerate with heat
Inhibition warning: Cure can be inhibited by nitrogen, sulphur, phosphorus, arsenic, organotin catalysts, epoxy resin catalysts, condensation-cure silicones, modelling clays, sulphur-vulcanised rubbers, onion and garlic. Use clean tools only.
