Our product portfolio covers Silicone Potting Compounds, Electronic Silicone Gels, Thermally Conductive Potting Compounds, Liquid Silicone Rubber, Silicone Rubber, Silicone Adhesives, Silicone Grease, Epoxy Potting Compounds, Polyurethane Potting Compounds, and other specialty silicone materials.

We serve demanding applications across electric vehicles, battery energy storage systems, solar inverters, LED lighting, electronics, electrical equipment, industrial automation, mold making, medical applications, and other advanced manufacturing industries.

Our goal is simple: to provide high-performance materials, consistent quality, responsive technical support, and dependable global supply for every customer we serve.

Hanast operates a large-scale manufacturing base designed to support both standard products and customized material solutions.

Our production capabilities allow us to respond efficiently to small-batch sample development as well as large-volume commercial production, helping customers maintain stable supply and predictable production schedules.

From raw material management and formulation to production, testing, packaging, and shipment, we maintain strict control throughout the entire manufacturing process.

At Hanast, technical capability is at the heart of our business.

Our R&D team focuses on developing and optimizing silicone materials according to specific customer requirements, including:

• Viscosity
• Hardness
• Curing speed
• Thermal conductivity
• Adhesion
• Electrical insulation
• Flame retardancy
• Flexibility
• Tear strength
• Temperature resistance
• Application-specific performance

Our engineers work closely with customers from the initial requirement stage through sample development, testing, formula optimization, and mass production.

This enables Hanast to provide application-oriented silicone solutions rather than simply supplying standard materials.

To ensure stable performance from batch to batch, Hanast has established professional testing and verification capabilities.

Our testing capabilities include:

Thermal Conductivity Testing

Used to verify thermal performance for applications such as EV battery management systems, electronic components, and power electronics.

Rheology & Viscosity Testing

Used to control flowability, viscosity, and processing characteristics for different dispensing and molding processes.

Tensile & Tear Strength Testing

Used to evaluate the mechanical performance and durability of silicone materials, particularly for mold-making and industrial applications.

Dielectric Strength Testing

Used to verify electrical insulation performance for electronic and electrical applications.

Quality control is integrated throughout the manufacturing process to ensure that products meet defined technical specifications before shipment.

Hanast understands that international customers require more than product performance. They also require documentation, regulatory compliance, and dependable export support.

Our materials are developed to meet demanding international requirements, with compliance and documentation support including:

• RoHS Compliance
• REACH Compliance
• UL 94 V-0 Flame Retardant Options
• Technical Data Sheets (TDS)
• Material Safety Data Sheets (MSDS)
• Safe Transportation Documentation
• International Export Documentation

Our quality management capabilities also include ISO 13485-related medical quality management experience, supporting customers with demanding medical and high-precision applications.

Every application is different.

That is why Hanast provides customized formulation and OEM/ODM services for customers who require specific material properties or processing characteristics.
