Stiffeners

Sheets or rolls

SIT EST

extrusions

  • Elastic, resilient, recycled, soft / semi-rigid / rigid thermoplastic and thermo-adhesive stiffeners.

  • Materials for use as toe-puffs and counters for footwear.

    SIT Est materials are ideal in the production of sneakers and sport shoes.

    The rigid version is suitable for the production of safety shoes, trekking shoes, sky boots and roller blades.

  • All materials SIT Est (extrusions) are sustainable and solvent free and some versions can be made with BIO polymers, compostable.

  • Available thicknesses from 0.3 mm to 2.0 mm in sheets 100 X 150 cm or in rolls height 100 cm and length 50 mt / 100 mt / 150 mt.

SIT CUT

shaped counters & toe puffs
automatically cut and skived counters & toe puffs

Extruded, impregnated (WOVEN and NONWOVEN) TPU and pressed powder materials can be "taylor made": cut, skived and shaped on patterns and shapes requested by the customer.

It is a service available on all SITEC stiffeners (toe-Puffs and counters), with a strong ecological and green impact.

Compared to sheet material deliveries, production waste and wasted materials is saved by about 25%, with a clear positive impact on the environment and waste disposal.

Warehouse costs are reduced accordingly.

SIT CUT material transports greatly reduce CO2 and fine dust emissions due to reduced transport volumes.

SIT CUT eco-friendly materials represent a further step forward in SITEC’s sustainability and environmental policies.

SIT TPU

extruded “in core adhesive” materials

SIT TPU materials for Toe Puffs and counters represent one of the excellence of the SITEC range.

They are thermoplastic and heat adhesive extruded materials; the adhesive is located inside the sheet material (it is not applied on the outer surfaces).

The polymers used in the making of the sheets derive from the families of polyurethanes and polyesters.

The areas in which the material is peeled and lowered, during the production of footwear or bags, turn out to be thermoadhesive without the need of subsequent application of adhesives, avoiding stages of additional processing in the production cycles.

All SIT TPU materials are recyclable and can be BIO compostable

TPU materials can be made with varying percentages of recycled polymers on demand, and with the addition of ecological and sustainable fillers, such as plastics derived from PET bottles, CD, marine plastics, wood processing waste or rice processing.
