We produce pultruded components offering premium value-added services, underscored by our prompt response time. With a team of seasoned engineers at the helm, we’re equipped to help design almost any continuous cross-sectional pultrusion profile you envision.

Polyurethane Pultrusion

Rhinotrusion specialises in crafting bespoke pultrusions harnessing the power of Polyurethane resin technology. Notably, urethane boasts a stiffness that’s 40% greater than Polyester. This advantage permits the creation of more rigid profiles or permits a reduction in profile thickness by approximately 25%, leading to lighter profiles while preserving the same rigidity offered by Polyester resin techniques.

The Pultrusion Process: STEP-BY-STEP

1. Raw Material Preparation: Before the pultrusion begins, all raw materials, including the continuous strand fibres (like fibreglass rovings), mats, and resin mixtures are prepped. The resin mixture usually consists of a polymer resin, catalysts, fillers, and other additives, which can give the end product certain desired properties.

2. Roving & Reinforcement: Fibreglass rovings are unwound from creels (large spools) and are guided to maintain their orientation. Depending on the product’s requirement, other reinforcements, like woven fabrics or continuous filament mat, can also be incorporated.

3. Resin Impregnation (Wet-Out): The guided reinforcements are then passed through a resin bath or impregnation system. In this stage, the fibres get completely saturated with the resin mixture, ensuring that they are fully wet-out. This is a crucial step, as the resin gives the final product its environmental and chemical resistance, while the glass fibres provide the strength.

4. Pre-forming: Once impregnated with resin, the material goes through a pre-forming guide to squeeze out excess resin and help in initial shaping. It also aids in removing trapped air and ensuring the uniform distribution of resin.

5. Heating & Curing: The wet-out fibres then enter a heated die. The die not only provides the shape to the pultruded profile but also heats the resin-infused fibres, causing the resin to cure (harden). The heat activates the catalysts in the resin mixture, and a polymerisation reaction occurs, bonding the fibres together and hardening the profile.

6. Pulling: Powerful pullers, usually consisting of clamps or grips, pull the now cured profile continuously from the die. The speed of these pullers dictates the production rate and ensures a steady output.

7. Cutting to Length: After exiting the die, the continuous profile is passed through cut-off saws or cutting mechanisms that trim the profile to the desired length.

FRP Pultrusion Insights

Rhinotrusion proudly delivers Fibre Reinforced Polymer (FRP) pultrusions, serving numerous industries with various applications. The pultrusion technique facilitates the production of extended lengths of FRP in distinct profiled shapes, outclassing many conventional construction materials.

Value Proposition of Pultrusion:

  • Non-conductivity.
  • Resilience against corrosion.
  • Strength combined with lightweight properties.
  • Versatility and cost-effectiveness.

Depending on the Polyglas pultrusion class, fire-retardancy can also be incorporated. Polyglas electrical pultrusion retains these merits and can also be tailored to be non-magnetic, UL certified, arc and track resistant, and fire-retardant.

Compared to Alternatives:

  1. Against Metal & Wood:
    • Pultrusions are remarkably lightweight—75% lighter than steel and 30% lighter than aluminium, benefiting sectors from transportation to aerospace.
    • Unlike metals with isotropic properties, FRP pultrusions can be reinforced where necessary, optimising efficiency.
  2. Versus Wood/Structural Timber:
    • Pultrusions resist rot, mold, warping, and insect infestation.
    • Even when wet, FRP remains non-conductive, enhancing safety.
    • Lighter than timber, yet sturdier and more rigid.
    • Rhinotrusion composites possess innate UV, weather protection, and corrosion resistance, eliminating the need for expensive treatments typical for wood.
  3. Versus Steel:
    • FRP offers non-conductivity, 75% reduced weight, and corrosion resistance, while retaining comparable or better strength.
    • Long-term costs often favor pultrusions due to reduced maintenance.
    • FRP pultrusions are radio wave transparent, making them suitable for various communication applications.
    • Easier fabrication and installation than steel.
  4. Versus Aluminium:
    • FRP outperforms aluminium in lightness, non-conductivity, and corrosion resistance.
    • Pultrusions have superior dimensional stability and impact resistance.
    • Long-term cost analysis often tilts in favour of pultrusions due to their longevity and reduced maintenance.

Polyglas Structural Pultrusion Benefits:

  • Corrosion and chemical resistance.
  • Non-conductivity.
  • Electromagnetic transparency.
  • Lightweight yet durable.
  • Impact-resistant and dimensionally stable.
