Polyester resins - Import export

Polyester resins (UP resins) form the basis of our product range in the glass fibre reinforced plastic systems business area – with a wide variety of applications. They range from thixotrope standard systems for manual lamination and fibre spraying to low-viscosity standard formulations for polymer concrete and sanitary applications to numerous special formulations for specific requirements. With a broad spectrum of properties and applications, our UP resin systems are suitable for products in a wide variety of industries. Typical properties Dense matrix / composite of approximately 1.1 g/cm³ / 1.5–1.7 g/cm³ Fibre content 25-50 % of total weight Moulded part mass per unit area of 4500-8000 g/m² Flexural modulus of elasticity 5000–25,000 MPa (with reinforcing mesh) Bending resistance of 130–260 MPa (with reinforcing mesh) Impact resistance of 45–95 KJ/m² Reinforcing materials: Continuous or cut glass fibre mats, fleece Mesh Non-crimp fabrics Special formulations and versions Styrene-reduced, environmentally friendly formulations Low-viscosity injection resins with reduced exothermic peak Formulations for the pultrusion process Systems with high chemical and hydrolysis resistance DIN 1140 versions with special mechanical values and dimensional stability under heat greater than 100 °C (HDT > 100 °C) Resins with good adhesion for combination with PVC Resin systems with shipping industry approval: Det Norske Veritas/Lloyd’s Register of Shipping/Germanic Lloyd Coordination with gel coat/top coat for surface refinement Flame protection formulations Electrical industry: UL 94 V0 Rail vehicle construction: DIN 5510 (S4, SR2, ST2)

In simple sealed moulds, glass fibre reinforced plastic components that are smooth on both sides are produced cost-effectively under a vacuum in comparatively short cycle times. The production of sandwich components resistant to bending, with a foam core, and the direct integration of metal reinforcements and threaded elements – for example for large vehicle components – has also proven itself. Typical properties Dense matrix / composite of approximately 0.6–0.7 g/cm³ / 0.7–1.2 g/cm³ Fibre content 20-50% of total weight Moulded part mass per unit area of 3000–5000 g/m² Flexural modulus of elasticity 3000–8000 MPa Bending resistance of 35–185 MPa Impact resistance of 35–65 KJ/m² (with 20–35% glass content) Reinforcing materials: Continuous glass fibre mats Composite glass fibre and fleece mats Natural fibre mats Special formulations and versions Systems with long processing times for very large components Foam resin formulations with elevated dimensional stability under heat Systems for fibre-reinforced components with a high level of characteristics Coordination with gel coat / top coat for surface refinement Flame protection formulations Electrical industry: UL 94 V0 Rail vehicle construction: DIN 5510 (S4, SR1, ST2)
