Product Overview
This product is developed and manufactured by Asahi Kasei and belongs to the Tuftec™ series of styrenic thermoplastic elastomers, chemically classified as SEBS (hydrogenated styrene-butadiene block copolymer). The material possesses fundamental physical and chemical characteristics including low density, high elongation, and a balance of elasticity and mechanical strength, achieving rubber-like elastic properties without the need for vulcanization. The material is compatible with thermoplastic processing logic and can be manufactured using two mainstream processes: extrusion molding and injection molding.

Logistics & Supply Standards
The standard packaging for Asahi Kasei Tuftec™ H1062 SEBS is a 25kg composite paper-plastic bag, and the finished granular form does not possess hazardous chemical properties. We maintain stable and safe inventory in globally cooperative warehouses. Standard delivery lead time for in-stock orders is 7-14 working days, while lead times for overseas cross-border orders are subject to international trade agreement terms. This product is not classified as a hazardous chemical. Storage and maritime shipping support mixed transport of multiple grades and categories of non-hazardous plastic raw materials. We can coordinate consolidated shipping based on buyer order requirements to reduce comprehensive logistics costs.
Compliance & Quality Commitment
Buyers may request the original paper or electronic versions of the TDS technical data sheet, MSDS safety data sheet, and COA factory quality inspection report, stamped with the original manufacturer’s official seal. This grade has completed REACH EU chemical registration, RoHS restriction of hazardous substances for electronics, and FDA food-contact material compliance certification, fully meeting the entry standards for mainstream European and American terminal industries. Full-chain production batch control is implemented for all raw materials, ensuring traceability from polymerization and packaging for storage to final delivery. Each batch of goods is accompanied by corresponding quality inspection files, with complete retention of production, testing, and outbound records to guarantee batch product performance stability and compliance traceability.
Sustainability & ESG Statement
Tuftec™ H1062 SEBS is a thermoplastic elastomer material. After molding and processing, waste and scraps can be directly recycled, granulated, and re-introduced into production. Without an irreversible cross-linked structure, it possesses the fundamental conditions for circular recycling. The raw material synthesis system optimizes low-volatility additive formulations, resulting in lower VOC emissions during high-temperature extrusion and injection molding compared to general vulcanized rubber materials, making it suitable for low-odor green product production requirements. The entire product production chain follows EU green supply chain control standards. The production plant executes closed-loop treatment processes for industrial wastewater and exhaust gas to reduce pollutant emissions in the chemical production stage, meeting the ESG supply chain audit requirements of global downstream brands.
Frequently Asked Questions (FAQs)
Q1: Does this SEBS grade require pre-drying before processing, and how are the drying parameters set?
A: Tuftec™ H1062 SEBS itself has extremely low water absorption and does not require drying for direct processing under standard storage conditions. If the raw material is stored in a high-humidity environment for a long period or used for high-transparency products, it can be hot-air dried at 80°C for 2-4 hours to remove surface-adsorbed moisture and prevent air bubble defects in the products.
Q2: What are common issues encountered during the processing of Tuftec™ H1062 SEBS and their solutions?
A: If the product surface appears rough during processing, it is usually due to insufficient plasticization temperature; it is recommended to appropriately increase the processing temperature. If air bubbles are found in the product, check whether it is due to moisture in the raw material and refer to the drying process settings. In addition, maintaining a suitable mold temperature helps improve the gloss and demolding effect of the product surface.
Q3: How to distinguish and select between H1062 and other SEBS grades in the same series with different hardness?
A: This grade has a Shore A hardness of 67, focusing on high-elongation, low-modulus elastic products. If higher support strength is required, grades with a Shore A hardness of 80 or above can be selected. If an ultra-soft touch is desired, models with a Shore A hardness below 50 should be chosen. Selection can be matched according to the product’s compression resilience and tactile hardness requirements.
