Custom Die Forms (CDF)

CDF products are commonly used in:

  • Gaskets and seals
  • Pads and spacers
  • Buffers and impact absorbers
  • Vibration- and noise-damping elements
  • Insulation and protective liners

Our CDF solutions serve a wide range of industries, including:

  • Automotive and mobility
  • Industrial equipment and machinery
  • Infrastructure and construction
  • Energy and utilities
  • Manufacturing and processing plants

Each solution is tailored to the functional and compliance needs of the sector.

CDF components are primarily produced from reclaimed rubber sourced from tyre sidewalls and other difficult-to-recycle rubber streams, ensuring durability, flexibility, and impact resistance while reducing reliance on virgin materials.

Yes. CDF products are fully customizable in terms of:

  • Shape and geometry
  • Thickness and density
  • Performance characteristics (compression, damping, resilience)
  • Dimensional tolerances

Our experts work closely with customers to translate performance needs into practical designs.

Custom Die Forms are precisely die-cut components manufactured from end-of-life tyres and recovered rubber materials, engineered to meet bespoke industrial and technical specifications. Each form is designed to deliver consistent performance while supporting circular material use.

Engineering Plastics

Suitable for automotive and industrial components, furniture, electrical and electronic systems, home appliances, and a broad range of engineering applications demanding durability, strength, and heat resistance.

Once you’ve registered your interest, our experts typically reach out within a week or sooner. We operate with an agile, highly responsive team, which means we often initiate the conversation earlier, depending on availability and the nature of your requirement. Our goal is to ensure prompt engagement, clear next steps, and a smooth start to the discussion—without unnecessary waiting.

We respond in a week, not in quarters. 

As per the clients’ demand, we tailor our compounds, ranging from 100% virgin to 100% recycled

Recycled nylon solutions offer a highly cost-effective alternative to virgin nylon, helping manufacturers manage raw material costs without sacrificing functional performance. By leveraging recovered feedstocks and optimized processing, these materials deliver stable and repeatable quality, with controlled mechanical, thermal, and processing characteristics suitable for a wide range of industrial applications.

Upscaled polyamide (recycled Nylon-6) recovered from tyre cords, ocean waste, and textile waste, engineered to meet performance needs while reducing reliance on virgin nylon.

Pyrova Energy

Pyrova Energy is GRP’s tyre pyrolysis initiative that converts end-of-life tyres into high-value outputs such as Tyre Pyrolysis Oil (TPO), carbon char (upgradable to recovered carbon black), and recovered steel using a fully automated continuous reactor system with a closed-loop energy setup. 

Pyrova stands for innovation-driven pyrolysis that converts waste tyres into commercially viable, sustainable materials—powering the circular economy.

Tyre Pyrolysis Oil (TPO) with a density of approximately 0.8–0.9 kg/m³; carbon char targeted for upgrade to recovered carbon black (fineness < 10 microns); and recovered steel wire.

Petrochemicals (as feedstock), tyre and rubber product manufacturing, paints and coatings (as pigments), plastics, and virgin carbon black production chains.

It diverts tyres from landfills, builds circular-economy pathways, reduces emissions via energy recovery (syngas), and creates long-term, responsible material streams.

Reclaim Rubber

Yes. We work closely with customers to customize reclaim grades based on:

Mechanical and processing requirements

End‑use application

Cost and performance targets

Using GRP's reclaim rubber helps customers:

Reduce dependence on virgin rubber

Cut carbon emissions and energy consumption

Divert tyre waste from landfills and incineration

Strengthen ESG and sustainability reporting

IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, with REACH compliance for EU markets.

We follow:

Established environmental and regulatory guidelines

Proper documentation and traceability practices

Ethical sourcing principles aligned with sustainability goals

Using our reclaim rubber supports compliance with:

Circular economy and waste‑reduction regulations

Customer sustainability commitments

ESG and responsible sourcing initiatives

Repurposed Polyolefins

Using Repurposed Polyolefins helps companies:

Reduce Scope 3 emissions

Meet recycled-content and EPR mandates

Strengthen sustainability reporting

Demonstrate tangible circular economy outcomes

While engineering polymers such as ABS and POM offer higher mechanical or thermal properties, repurposed PP can replace them in selected applications through material engineering, including:

Fillers and reinforcements (mineral-filled or fiber-modified PP)

Impact modifiers to improve toughness

Blended formulations to balance stiffness, processability, and cost

This approach allows manufacturers to:

Achieve adequate performance for non-critical parts

Significantly reduce material costs

Improve sustainability by lowering carbon footprint


Such substitutions are increasingly adopted in automotive interiors, consumer products, and industrial components where extreme performance is not essential.

Repurposed Polyolefins offer strong commercial advantages by:

Cost competitiveness versus virgin polymers, especially during feedstock volatility

Helping brands comply with mandatory recycled-content regulations

Enabling access to sustainability-driven customers and markets

Reducing supply-chain risk by diversifying away from fossil-based materials


As demand for recycled polymers rapidly increases, businesses using Repurposed Polyolefins gain both cost resilience and regulatory readiness.

Repurposed Polyolefins play a vital role in the circular economy by:

Converting end-of-life plastics into high-value raw materials

Reducing dependence on virgin polymers

Lowering CO₂ emissions associated with polymer production

Minimizing landfill disposal and plastic leakage


This enables manufacturers to meet ESG, EPR, and recycled-content targets without compromising functionality.

Repurposed Polyolefins are polyolefin-based materials derived from recycled plastic waste streams and reformulated to deliver reliable performance with sustainability advantages. These materials are engineered to suit industrial, consumer, and packaging applications where durability, processability, and environmental impact are equally critical.
