NaugaShield BIO-TR 30: A New Bio-Based Cut & Chip Resin For The Most Demanding Applications
- By TT Bureau
- July 16, 2026
NaugaShield BIO-TR 30 is SI Group’s latest advancement in bio-based performance resins designed to significantly improve cut and chip
resistance in high-severity rubber applications. With approximately 75 percent bio-based content, this innovative material delivers on sustainability targets while exceeding the performance typically associated with petroleum-derived resins, making it a strong choice for applications such as OTR tyres in mining, construction and agriculture, mining conveyor belts, rubber tracks and mill linings.
Cut and chip resistance is a complex set of material behaviours, including static mechanical strength, dynamic response under deformation and ability to withstand sharp impacts and abrasive environments. In demanding applications such as mining or agriculture, materials
must tolerate repeated high-strain loading and resist the initiation and propagation of tears. NaugaShield™ BIOTR 30 was developed precisely to meet these conditions, demonstrating notably low dynamic heat buildup and excellent tear strength – characteristics closely tied to enhanced cut and chip resistance and long-term durability under cyclical loads.
To evaluate its performance, NaugaShield BIO-TR 30 was benchmarked in an Off-road Rib Tread formulation against two widely used industry references: a gum rosin/ semi-aromatic C5/C9 resin combination and a styrenated DCPD resin. All materials were tested at an equal loading of 10 phr to provide a direct and unbiased comparison. Under these conditions, the bio-based resin consistently outperformed both alternatives, offering a stronger balance of reinforcing behaviour, improved tear propagation resistance and superior resistance to thermal degradation during dynamic flexing. Further improvements were achievable by reducing the amount of free extender oil in the compound, underscoring the resin’s adaptability in formulation design and its ability to unlock even greater performance when optimised.
These laboratory indicators were corroborated through extended Coesfeld Cut & Chip testing (see chart), in which compounds were subjected to up to 3,000 cycles at 200 rpm under a 200N applied force. Formulations containing NaugaShield BIO-TR 30 exhibited substantially lower mass loss and maintained tread surface integrity more effectively than the hydrocarbon and gum rosin-based-benchmarks. The performance advantage was even more pronounced in compounds adjusted for lower free oil content, confirming that the resin can be tailored to meet the durability requirements of the most challenging operating conditions.
The strong performance of NaugaShield BIO-TR 30 in OTR tread compounds can be readily transferred to other rubber goods that encounter similar wear mechanisms. Applications such as mining belts, agricultural and construction tracks or mill linings benefit from the resin’s ability to reinforce the rubber matrix, reduce crack growth under repeated impact and maintain structural cohesion under high-strain deformation. This versatility allows manufacturers to integrate a 75 percent bio-based resin that supports sustainability by reducing fossil-based content and helping end products last longer while maintaining – and often improving – operational performance across multiple product lines.
NaugaShield BIO-TR 30 is currently available in commercial quantities, enabling compounders and manufacturers to move directly from laboratory evaluation to pilot- and production-scale trials.

- July 15, 2026
Natural Rubber (NR) plantations developed under Project INROAD (Indian Natural Rubber Operations for Assisted Development) have reached 179,376 hectares across north-east India after the completion of planting for the 2025-26 financial year, bringing the initiative close to its original target of 200,000 hectares.
Launched in the 2021-22 financial year, the project has established new NR plantations across 113 districts in the region over the past five years. According to the project partners, this represents the country's largest expansion of natural rubber plantations achieved within such a period.
Project INROAD is funded by tyre manufacturers Apollo Tyres, CEAT, JK Tyre and MRF, and is implemented by the Rubber Board of India. It is described as the first initiative of its kind in which the Indian tyre industry directly supports the development of rubber plantations.
"Despite several operational challenges including Covid-induced disruptions in the beginning, nearly 90% of the ambitious target of 2 lakh hectares of new plantation has been achieved under Project INROAD during the last five years. Beyond plantation expansion, the project has also made significant progress in strengthening local nurseries and building grower capacities — a testament to the collaborative efforts of the tyre industry and the Rubber Board," said Mohan Kurian, chairman of Project INROAD.
The project has distributed a record 83m quality planting materials during the five-year period. It has focused on supporting resource-constrained communities in the designated states, particularly small and marginal farmers, most of whom own less than one hectare of land. More than 200,000 beneficiaries have been supported through the initiative, with the project aiming to improve livelihoods and promote socio-economic development.
Project INROAD has also expanded nursery infrastructure across the region. More than 200 nurseries are supplying high-yielding planting materials to growers, while new and improved rubber clones suited to the north-east's agro-climatic conditions are being distributed through the programme.
"With plantations reaching a critical stage, the next component of the project — development of supporting infrastructure such as model smokehouses and dissemination of improved practices among rubber growers — is progressing well under the INROAD Skilling and Production Efficiency Enhancement Drive (iSPEED) initiative," Kurian added.
Under the iSPEED initiative, infrastructure development is intended to improve the quality of rubber produced by farmers through value addition at source. The programme also plans to roll out large-scale digital and in-person training for growers, supported by newly developed training materials that are ready for release.
