ALTA Unsaturated Polyester Resins (UPR)
ALTA Performance Materials offers a world-class portfolio of thermoset resins for Composites manufacturing. Unsaturated Polyester Resins are utilized in numerous high-volume applications that touch our everyday lives. Available through Nordmann, these resins serve applications across Building & Construction, Marine & Recreational, Transportation, Corrosion and Infrastructure. ALTA Performance Materials’ technical service team brings an industry-leading reputation for collaborative problem-solving, recommending the right product for each fabrication process and end-use environment.
Unsaturated Polyester Resins (UPR)
Unsaturated Polyester Resins offer excellent processability, design flexibility and weight savings over traditional materials. The manufacturability, design allowance and weight savings that are commonplace with FRP and Cast Polymers make UPR resins a popular choice.
ALTA Performance Materials' UPR portfolio through Nordmann covers the full range of Composites fabrication needs:
| Application Need | Solution | Brand |
|---|---|---|
| General lamination & structural build-up — Hand Lay-Up, Spray-Up, RTM and Pultrusion processes requiring flexible reactivity, viscosity and gel time control | Engineered general-purpose UPR with high mechanical and impact properties, customisable to your process parameters | AROPOL® |
| Automotive & rail body panels — SMC and BMC compression moulding where Class A surface quality and dimensional precision are required | Transportation-grade UPR optimised for closed-mould pressing, delivering low shrink and smooth surfaces when combined with LPA | AROTRAN® |
| Sanitary ware, solid surface & cast polymers — baths, shower trays, basins and engineered stone where surface aesthetics and scratch resistance are non-negotiable | Premium UPR providing excellent surface finish, scratch resistance and long-term dimensional stability | POLARIS® |
Processing Compatibility
ALTA Performance Materials’ resins are compatible with the full range of Composites manufacturing processes used by Nordmann's customer base:
- Open mould: Hand Lay-Up (HLU), Spray-Up
- Closed mould: Resin Transfer Moulding (RTM), Vacuum Infusion
- Compression moulding: SMC, BMC
- Continuous: Pultrusion, Filament Winding
- Casting & Pouring: engineered stone, solid surface, polymer concrete
ENVIREZ® Sustainability Platform
Sustainability in composites starts with smarter material choices. ALTA Performance Materials’ ENVIREZ® Sustainability Platform integrates recycled and renewable materials designed to reduces reliance on virgin resources while delivering high-performance solutions.
Why choose more sustainable resins?
- Reduce volumes of plastic waste entering landfill or incineration
- Save natural resources and energy compared to virgin raw material production
- Lower carbon footprint impact across your Composite parts
- Deliver the same strength, flexibility and cost-competitiveness as standard industry resins
Low Profile Additives (NEULON®)
Enhance your resin system with ALTA Performance Materials’ NEULON® Low Profile Additives (LPA).
When processing ALTA Performance Materials’ UPR or VER resins in SMC, BMC, Pultrusion or RTM systems that require low/no-shrink characteristics and Class A, high-gloss surfaces, NEULON® LPA resins are the complementary solution. NEULON® controls shrinkage during cure and enables smooth, dimensionally accurate Composites parts without post-processing. Ask our Composites team for system recommendations that combine ALTA Performance Materials’ resins with NEULON®.
