Poolkemie provides a large range of polyurethane resins (pure, charged, foams) with different properties, according to specific application

Bi-component polyurethane (Polyol and Isocyanate) pouring resins, that cure at room temperature, with addition of the appropriate hardener, forming a stable and not reversible compound with high mechanical resistance. Are characterized by very small linear shrinkage, quick demoulding, high crash and scraping resistance, dimensional stability and excellent surface finish. Owing to their fluidity they go deep into the moulds reproducing exactly any smallest detail of it.

Resins are chargeable, using very light charges it is possible to obtain products with low specific gravity in different applicative sectors.

Main features

Very little linear shrinkage (no linear shrinkage if charged)
Extreme faithfulness in the reproduction of details from any original model
Excellent surface finish
High crash and scraping resistance
High temperature resistance
Waterproof properties
Excellent dielectric properties
Easy mould building, no need of particular equipments
Adding appropriate charges it is possible to give to the resin special properties

Properties of polyurethane resin and types

Applicative sectors

Industry Production of rigid moulds (pilot vacuum thermoforming moulds), foundry patterns, copy/negative models, small/medium sized articles, protective encapsulation of equipments useable mainly in high technology sectors (electric-electronic and electrotechnical), semi conductors gasket protection, dielectric insulating of machines or materials for flow-coating or painting.
Rapid prototyping Production of demonstrative prototypes.
Modelling Serial reproduction of small sized resin articles, model in scale of cars, ships, airplane, toy-soldiers. Silicone rubbers are used to make the moulds in order to assure faithfulness in reproducing original model forms and details. Reproduction is obtained by pouring the resin into the mould.
Handicraft Reproduction of handicraft resin products.

PURE POLYURETHANE RESINS

RESIN PU 087 (HARDENER PUH-887)

Special bi-component pourable polyurethane resin. Characterized by low viscosity, high thermic resistance (up to 110°C), low linear shrinkage, quick demoulding, excellent definition. Suitable for producing demonstrative prototypes, foundry patterns (where it is required excellent wear resistance, dimensional stability and high precision), negatives, serial poured hand-made articles, copy models, blister, pilot vacuum thermoforming moulds or similar applications. The resin is pigmentable and highly filleable (using the charge AL 3 H it is possible to obtain low specific weight products). Available standard catalyst for thin layers and slow catalyst for relevant masses.

RESIN PU 880 CE

(HARDENER PUH 880 B) Fluid and free from solvent polyurethane system. Excellent mechanical and electric properties, high tenacity and thermal shock resistance. Encapsulation and sealing of electric components. Armoured resistance. Applicable by pouring, vacuum casting.

CHARGED POLYURETHANE RESINS

RESIN PUC 097 (HARDENER PUH-1097)

Bi-component polyurethane resin applicable by pouring, pre-filled with special charges, tool workable. Characterized by no linear shrinkage (<0,05%), high scraping and thermic resistance (up to 115°C). Used for the realization of foundry patterns, copy models, moulds and prototype, pilot vacuum thermoforming moulds, in modelling sector (realization of models in scale of cars, ships, airplane, toy soldiers, small objects). Available standard catalyst for thin layers and slow catalyst for relevant masses.

POLYURETHANE RESINS VACUUM CASTING

Special vacuum pouring polyurethane resins, transparent and UV resistant. Physical and mechanical properties similar to PVC, PP, PE, ABS, PMMA, PC, Nylon, used for the production of functional models. Thermic resistance over 200°C. Hardness from 40 to 90 shore A.

POLYURETHANE RESINS R.I.M.

Bi-component polyurethane systems similar to polypropylene. Cure at room temperature, low viscosity, quick delivery (demoulding), high thermic resistance (oltre 180°C). Used in rapid prototyping field and for limited serial productions.

Poolkemie products are simple to use, technically innovative and provided with high mechanical characteristics.
