Our machining workshop, with manual lathes, numerical control lathes, automatic and CNC lathes, allows us to manufacture any type of part in any technical plastic.

We have curing ovens with forced hot air reciculation of the latest technology.

These ovens allow us a superior quality production since our silicone profiles, both compact and spongy silicone, receive a contant and homogeneous temperature during the curing process, reducing the chances of rejection, as well as its tolerances

In our compounding facility we prepare the silicone raw material and add it with the necessary chemicals according to our customers' needs.

We manufacture compounds to measure, for those customers who need specific solutions. Tell us your requirements and we will help you to find your silicone.

Starting from 25 kg batches, we can manufacture any compound and colour.

They have at their disposal one of the largest stocks of sponge silicone sheets, with thicknesses available permanently from 2mm to 25mm in white raw.

Ask our sales department and they will advise you on high density silicone sponge, foodstuff contact sponge silicone sheet and coloured silicone sponge.

Our extensive stock of compact calendered silicone sheets allows us to offer our customers compact silicone sheets in thicknesses from 0.3mm to 15mm, in hardness 40, 50 and 60Shore A in translucent colors, white, red tile, blue and black.

Consult with our commercial department and they will be able to advise to them, on the plates of silicone of high temperature (+250ºC), plates of platinum silicone, fluorosiliconas, detectable silicones, etc.

Smooth, non-stick, thin wall PTFE fluoropolymer tubing with inner diametres fro 0.25mm up to 25mm with minimum order quantity.

Ask for our stock of standard dimensions such as: 2x4 , 4x6 , 6x8 , 8x10 , 10x12 , etc.

More than 3000m2 in stock of ptfe coated glass fabrics in different standard thickness, with and without adhesive backing. We can thus deliver in 24-72 hours to any place in Europe.

We have a highly specialized staff and cutting workshop, which allows us to offer you almost immediately any roll of PTFE impregnated fabric in widths from 5mm

Starting from 1.6mm cross section up to 25.4mm, we can supply encapsulated o-rings in silicone and viton core with FEP and PFA outer layer in any inner diameter.

Minimum orders from 120€, ask us if you want to combine different dimensions and qualities. Our standard delivery time is 12 working days.

We also supply standard encapsulated rectangular gaskets for cam & groove locks.

Our wide range of immediate delivery convoluted PTFE, FEP and PFA hoses include from 8mm (5/16") to 125mm (4") inner diametre. On request we supply antistatic graphite-filled PTFE tubing and very thin wall tubing for very closed bends.

Manufacture of Zone-tapes to measure, the side adhesives can be different width to obtain an off-centered tape. Ptfe coated glass fabric slit rolls from 5mm width and 30 metre length. We have thicknesses of 0.08mm , 0.13mm , 0.16mm and 0.25mm for immediate supply with and without adhesive.

In Merefsa we manufacture any tape, band or mesh in glass fabrics impregnated with PTFE, silicone or aramid and any length.
