Silicone rubber KDSV THX-30 (set of two components)

 
 

Rate item

Description

KDSV THX-30 is a brushable, condensation curing 2-component silicone rubber with high elasticity for replicas using cast ceramic, plaster, polyester, polyurethane and epoxy casting resins. The resistance to epoxy resin systems is limited. However, at least 10 mouldings can usually be done before the surface of the silicone rubber shows visible wear. However, this depends on the epoxy resin system used as well as on the temperature during curing and the mechanical stress during demoulding. The silicone rubber KDSV THX-30 is food-safe and can be used for culinary applications. (US FDA approval* has been obtained).

To be able to apply KDSV THX-30 by spatula, Thickening agent C is used.

  • Good brushability(< 0.5 mm film thickness)
  • Fast vulcanisation at room temperature
  • Good tear strength and tear propagation strength
  • Food-safe

Technical data:
Possible mixing ratios: 100 : 2
up to 100 : 5 parts by weight silicone : catalyst
Processing time (approx. 23 °C / approx. 100 g mixture): 90 minutes (100 : 2) / 30 minutes (100 : 5)
Curing time: 12 h
(100 : 2) / 5 h (100 : 5)
Colour: White
Dyeing: R&G Universal Color Pastes (colour differs because of the basic colour of the silicone)
Mixing viscosity: 35.000-40.000 mPa·s
Density: 1.09 g/cm³
Shore A hardness : 35
Tensile strength: ≥ 4.2 N/mm²
Elongation at break: ≥ 420 %
Tear resistance: ≥ 25 N/mm
Linear shrinkage: 0.2 %

No heat of reaction occurs during vulcanization, so that even larger quantities (e.g. 10 kg) can be poured without the risk of overheating.

*Approval by the Food and Drug Administration for food production (source: Reichelt Chemietechnik)
The Food and Drug Administration has very strict requirements for food produced in or imported to the United States. These measures were adopted to prevent national disasters caused by contaminated or polluted food. Only companies that work in accordance with FDA and whose materials are certified accordingly are allowed to serve the US market.

FDA-compliant requirements make materials necessary that have a long shelf life and do not release any ingredients into the food. In the food sector, a large number of plastics with fundamentally different properties are used and come into contact with food. All these plastics must be FDA-compliant and their requirements selected accordingly.
