Poolkemie provides a large range of RTV2 silicone rubbers (poly-condensation and poly-addition) with different properties, according to specific application.
RTV2 silicone rubbers are liquid or pasty silicone elastomers reticulating at room temperature. After the addition of appropriate catalyst they form a stable and not reversible compound characterized by high elasticity and mechanical resistance. Owing to their high chemical-mechanical properties combined with easy workability, the RTV2 silicone rubbers are suitable for making flexible moulds and matrices to reproduce, starting from an original model, hand-made articles of any kind and form, in different applicative sectors. Silicone moulds, owing to their anti-adherence features, allow an easy demoulding of models and assure extreme faithfulness in the reproduction of details.

Main features
- Cold vulcanize with the appropriate catalyst
- Can be applied by direct pouring or by spreading
- Easy mould building, no need of particular equipments
- High elasticity, easy demoulding also for objects with undercuts
- Extreme faithfulness in the reproduction of details from any original model
- Odourless and no toxic
- Anti-adherent (no need of release agents for demoulding)
- poly-addition curing: low linear shrinkage and higher stability in time

Applicative sectors
|
| Sector |
Description |
| Industry |
Moulds for production of natural and synthetic wax decorative candles, of element for garden furniture, technical articles, toys etc… Some particular kind of RTV2 silicone rubbers are used in the shoe industry for the creation of aluminium matrices to reproduce soles for footwear. Special silicones for food sector (cake shop moulds, chocolate). |
| Architectonic restoration |
Moulds for the reproduction and restoration of plaster or cement architectonic features (decorated columns, rosettes, etc…), starting from an original model. RTV2 silicone rubbers are used in this field for their extreme faithfulness in the reproduction of details. |
| Applied Arts and artistic foundry |
Moulds for the reproduction of statues, cornices and artistic works, religious articles, friezes of wood imitation, artistic ceramics. Moulds for the production of bronze statues using the lost-wax method. Owing to their high temperature resistance, some particular types of elastomers are also suitable for the use in the artistic foundry, allowing to pour low-melting point alloy into the mould. |
| Building |
Moulds for production of precasted concrete elements. |
| Rapid prototyping |
Moulds for production of prototypes. |
| Modelling |
Moulds for the serial reproduction of resin articles (for example models in scale of ships, cars, airplane, toy-soldiers). Silicone rubbers are used to make the moulds in order to assure faithfulness in reproducing original model forms and details. Pouring polyurethane resins are the most used materials for reproducing models. |
| Handicraft |
Moulds for the production of handicraft articles in resin or plaster. |
| Pad printing |
for the production of inking-pad for thermoplastic ink printing. |
| Special effects and scenography |
Moulds for the production of static scenery. The elastomer can be also used to reproduce characters, animals, scenographic articles etc… |
