FAQs – Generic Masterbatch Solutions

  • KONSPEC delivers a complete masterbatch portfolio covering every essential need in polymer processing: COLOSOL® for colours, PERSOL® for additives, PROSOL® for processing aids, ECOWHITE for CaCO3-filled solutions, TRANSFILL for talc-filled grades, and ALPHA for performance enhancement. Together, they address the entire spectrum of colour, functionality, and productivity.

    1. Our formulations work across all major plastics processing methods: extrusion, injection moulding, blow moulding, rotational moulding, and thermoforming. This ensures consistent colour strength, dispersion quality, and functional performance regardless of the process.

  • Each COLOSOL® colour masterbatch is manufactured to deliver Delta E less than 1 shade consistency and FPV less than 1 per DIN EN 23900-2015, ensuring uniform colour reproduction and clean dispersion across every batch, even during extended, high-volume production.

  • Absolutely. KONSPEC offers dedicated COLOSOL® grades designed for PCR and PIR recycled polymers, enabling processors to achieve stable colour performance while supporting sustainable and circular manufacturing models.

  • Our solutions support a wide range of sectors including packaging, agriculture, automotive, infrastructure, consumer goods, electrical and electronics, wire and cable, hygiene, and industrial products. KONSPEC's generic masterbatches deliver the consistency, functionality, and processing efficiency required for competitive, high-quality manufacturing.

FAQs – Customised Masterbatch Solutions

  • KONSPEC designs customised masterbatches through close technical collaboration with each customer. Every formulation is tailored to the polymer, processing method, and end-use conditions, delivering ΔE < 1 shade accuracy, precise functional performance, and full regulatory compliance—far surpassing off-the-shelf alternatives.

  • Our customised solutions meet the world's most respected compliance frameworks, including FDA 21 CFR 178.3297, EU 10/2011, IS 9833, IS 9845, GB 4806.7-2023, EN 71-3, ASTM F963-17, ISO 8124, IS 9873, RoHS, WEEE, REACH, and SVHC. This covers food-contact safety, toy safety, environmental norms, and electronics regulations.

  • Our NABL-accredited laboratory ensures every customised masterbatch meets global performance and compliance standards. The lab verifies colour accuracy (CIE Lab), dispersion quality (FPV), regulatory compliance, and batch-to-batch consistency, ensuring every shipment is validation-ready and production-safe.

  • COMBIKON® combines colour and functional additives including UV stabilisers, antioxidants, antistatic agents, antimicrobial additives, slip/anti-block packages, and PPAs into a single, high-performance masterbatch. Choose COMBIKON® when your application demands colour and functionality together, such as in UV-protected agricultural pipes, antistatic electronic storage bins, and complex moulded components needing PPA support.

  • KONSPEC supports manufacturers across packaging, agriculture, telecom, automotive, consumer goods, medical/healthcare, and industrial sectors. Our customised solutions deliver precision colour, functional reliability, and certified compliance, making them essential for high-performance and regulatory critical applications.

FAQs – Engineering Plastics

  • This is a high-intent question because processors switching from commodity to engineering polymers actively search for this. It opens the door to KONSPEC's resin-matched carrier systems and the compatibility advantage of COLOSOL® and PERSOL® over generic solutions.

  • Polymer-specific compatibility queries are among the most searched in B2B plastics. Buyers working with engineering resins want to know upfront whether a masterbatch will work with their specific substrate without degrading mechanical properties.

  • This captures engineers and procurement managers researching UV stabilisers, antioxidants, and flame retardants for demanding applications, which is directly aligned with the PERSOL® range.

  • Compliance-driven searches (RoHS, REACH, FDA, EN 71-3) are growing rapidly, particularly from buyers in regulated industries. This FAQ positions KONSPEC's Global Regulatory Compliant and ASSURED® ranges squarely in the frame.

  • This question is increasingly searched as processors look to simplify their supply chain and reduce SKUs, which is precisely what COMBIKON® addresses and what sets it apart from single-function solutions.

FAQs – Sustainable Materials Group

  • Natural Fibre Composites (NFCs) are engineered materials that combine renewable bio-fibres such as rice husk, bamboo, wood flour, and jute with polymer matrices like PP and PE. They are used across automotive, appliance, consumer durables, and building industries as a high-performance, eco-responsible alternative to conventional plastics.

  • Yes. GreenPro Certified NFC compounds deliver high specific strength, stiffness, and dimensional stability, making them fully comparable to conventional plastic materials in demanding applications. They also resist corrosion, reduce equipment abrasion, and maintain performance across a wide range of processing methods.

  • NFCs replace fossil-based plastics with renewable bio-fibres containing up to 40% bio-content, substituting old carbon with new atmospheric carbon. This directly supports carbon reduction targets and circular economy goals for manufacturers seeking greener material solutions.

  • Yes, KONSPEC's NFC materials are fully recyclable and manufactured using low energy processes, making them a strong fit for brands committed to sustainable production. They can also incorporate agro-waste and recycled polymers, further advancing true material circularity.

  • NFCs are suited to a wide range of sectors including automotive components, consumer electronics, garden products, household goods, industrial packaging, and sustainable construction. Their versatility, aesthetic appeal, and customisable formulations make them an ideal material choice for manufacturers across multiple industries.

FAQs – Biocompostable Materials Group

  • Biodegradable plastics break down over time but may leave behind residues and can take years to degrade. Compostable materials, such as n2n® biopolymers, break down completely into water, carbon dioxide, and biomass within 90 to 180 days under industrial composting conditions, leaving no toxic residue and enriching the soil in the process.

  • Credible bio-compostable materials should carry internationally recognised certifications such as EN 13432, ASTM D6400, and ISO 17088. n2n® materials are certified under these standards, along with CPCB approval, CIPET certification, and GreenPro EcoLabel, ensuring genuine environmental performance rather than greenwashing.

  • Yes. n2n® materials comply with FSSAI standards IS 9833 and IS 9845, as well as USFDA and EU 10/2011 regulations, making them suitable for direct food-contact applications including flexible packaging, cutlery, cups, trays, and straws.

  • High-performance compostable compounds are typically formulated using PLA (Polylactic Acid), PHA (Polyhydroxyalkanoates), PBAT (Polybutylene Adipate Terephthalate), PBS (Polybutylene Succinate), and PCL (Polycaprolactone). n2n® products are engineered from high-purity grades of these renewable polymers, designed for both rigid and flexible applications.

  • Yes. n2n® bio-compostable compounds and masterbatches are formulated for compatibility with standard processing equipment used for injection moulding, extrusion, and thermoforming, enabling manufacturers to transition from conventional plastics without significant capital investment.
