insulating and foaming

A common application in every workshop is insulating or rather separating positive or negative moulds and the subsequent fabrication of a new fitting. For this working steps, BEIL offers the optimal separating agents and PUR foam systems.

Insulating / Separating

In addition to impeccable moulding, the basic requirement for working successfully with polyurethane foam systems is the reliable separation between mould and model as well as between mould and workpiece. Next to mechanical aids or sprays, liquid separating agents produced from various raw materials are used for this purpose. Depending on the type of application they provide optimal work results. Particularly worthy of mention in this respect is the separating agent 65/98, an unrivalled silicone separating agent, suitable for insulating even humid plaster casts.

All separating agents


Fittings made of foamed polyurethane (PUR) are very common in the orthopaedic workshop. This method provides good results, can be rapidly and affordably implemented and the fittings are ideally prepared for further processing.

Various systems are the basis for a wide range of applications for light to heavy components, rigid or flexible and cover all frequent requirements.

PUR rigid foam

The polyurethane (PUR) liquide foam systems of BEIL are user-friendly and made of high quality. Several product lines, each with different settings and formulations, offer all possibilities required in the orthopaedic workshop. Our PUR rigid foam systems guarantee a consistent and fine-pored quality at the highest level. Rigid foams are mainly used for models, leg and foot lasts as well as short leg compensation.


In orthopaedics, ASTI-OP is a synonyme for high-grade PUR rigid foams. BEIL provides the right product for every application to fabricate workpieces with bulk densities from 100 to 700 kg/m³. The use in practice of these products has been proven for decades. They were and are continuously further developed and offer an excellent price-performance-ratio.



ALPHA-PLAST PUR foam is the consistent development of the former Degaplast PUR rigid foams. ALPHA-PLAST is fine-pored and provides a longer processing time due to a significantly delayed reaction. ALPHA-PLAST workpieces are characterised by very low shrinkage and high heat resistance.

Alpha-Plast Foams


ASTI-L PUR rigid foam mainly corresponds to ASTI-OP, but at least with a longer processing time due to a significantly delayed reaction. This allows, for example, the foaming of several lasts in one single process.

Asti-L Foams


ASTI-V has been specially developed to fabricate short leg compensations. The PUR rigid foam has an ideal weigth due to its density of 170 kg/m³ and a reduced brittleness.

ASTI-V Foams

Pur flexible foams

BEIL PUR flexible foams ASTI-TECH and ASTI-S are used for the fabrication of custom-made insoles, forefoot and toe joint replacement as well as for seating shells, orthopaedic seat cushions and other paddings.
All foams have an open-cell structure and are offered with different characteristics and appropriate additives to fabricate custom-made fittings.


PUR flexible foam with very good resilience characteristics. Special formulations are possible and can be found in the Product Information.

Filling and Moulding

BKF putties have been optimised for the use in orthopaedics. They allow subsequent modification of moulds made of PUR foams and other materials such as wood, gypsumen moulding compounds.

Particularly suitable for PUR rigid foam moulds is our partially flexible polyester putty BKF Putty C-PLUS.
