Shanghai Huitian New Material Co., Ltd Latest company case about HUITIAN Capacitor Potting Compounds Provide Reliable Encapsulation for Demanding Electrical Applications

Reliable Protection for Capacitors in Demanding Environments

Capacitors are the heart of countless electrical and electronic systems, from automotive electronics and industrial equipment to consumer electronics and new energy applications. However, they face constant threats from moisture, vibration, thermal shock, and chemical corrosion — threats that can shorten service life and compromise performance. HUITIAN New Material, a professional manufacturer of high-performance potting compounds, provides complete encapsulation solutions that shield capacitors from these risks and ensure long-term, reliable operation.

Complete Solutions for Every Encapsulation Need

HUITIAN’s capacitor potting compound portfolio covers two major series — Epoxy Resin and Polyurethane (PU) — enabling customers to select the ideal protection for their specific application requirements.

Epoxy Resin Series: Rigid, High-Strength Protection

Designed for applications that demand maximum rigidity and durability, the epoxy series (Models 6318LB, 6319, 6211 and 6315) cures into a tough, high-hardness protective layer that delivers:

• Excellent electrical insulation for safe operation in high-voltage environments
• Superior chemical corrosion resistance for harsh industrial conditions
• Outstanding heat-aging resistance and long-term mechanical strength
• Excellent thermal-shock resistance that minimizes the risk of cracking

The series offers flexible processing options, including room-temperature and heat curing, along with environmentally friendly, halogen-free and antimony-free formulations.

Polyurethane (PU) Series: Flexible, Impact-Resistant Encapsulation

For applications where shock absorption and flexibility are critical, the PU series (Models 8250 and 8260) cures into a resilient elastomer that provides:

• Excellent low-temperature impact resistance for cold-climate reliability
• Superior resistance to temperature cycling and thermal stress
• Strong adhesion to a wide range of substrates
• Low curing stress that protects delicate components
• Excellent moisture resistance for humid environments

With dedicated solutions for bottom-layer potting (Model 8250) and surface-layer potting (Model 8260), the PU series enables complete, stress-free encapsulation of capacitors.
