Gap Fillers
Our liquid-dispense, cure-in-place gap fillers provide low stress on components and improve thermal resistance when compared to thermal pads. As batteries for electric vehicles become smaller and higher performing, they produce more heat which must be dissipated safely. Our gap fillers combine high thermal conductivity and low viscosity with the ability to maintain insulating properties.

Potting and Encapsulation
Our encapsulant and potting solutions provide a robust thermal management interface resulting in reliable products for you and your customers. These materials improve performance by optimizing heat dissipation with high thermal conductivity and low viscosity. They also protect components from dust and moisture and help reduce vibration.

Structural Adhesives
Whether you need structural integrity or an improved thermal connection, these products allow design flexibility and the ability to bond a variety of substrates including bare metal, painted metal, composite, rubber-to-substrate, and more. Our CoolTherm adhesives couple high-bond strength with thermal conductivity for ease of use and cost-savings. Customers use our adhesives for battery box assembly, hem-flange and composite bonding and body-in-white applications.

CliPHvent vent valves protect housings against mechanical damage that may occur in the event of pressure differences between the interior of the housing and the environment. The venting function is very important particularly in the event of a thermal runaway of battery cells and considerably contributes to the safety of battery systems.  

​CliPHvent vent valves enable fast venting via the integrated seal in case of a thermal event. Minor pressure differences between the interior of the housing and the environment due to air pressure or temperature changes are compensated via a membrane. 

In addition, Parker aspire® membranes are water- and oil-repellent. As a result, CliPHvent vent valves provide reliable protection against ingress of external liquids and dirt.

Benefits:

• Fast venting in case of thermal event
• Controlled pressure compensation in case of minor pressure differences
• Easy installation without tools
• Compact design
• UL 94 V0 flame retardation classification (please inquire)  
• Meets IP6XK, IPX6K, IPX9K, IPX7, IPXXB requirements against ingress of dust, water

THERM-A-GAP™ materials deliver lower thermal impedance, and higher thermal conductivity and greater compliance and conformability to automotive electronics. They are designed to enhance performance and reliability, guaranteeing a longer service life. 

THERM-A-GAP Gels are dispensable, pre-cured, single component compounds available with a thermal conductivity from 1 W/m-K to 12 W/m-K.  Their cross-linked gel structure provides superior long-term thermal stability and performance.

THERM-A-GAP CIP series are two-component, cure-in-place materials and are designed to be an alternative to hard-curing dispensable materials but also an improvement over application methods associated with thermal gap pads. Two materials are available with a 3.5 W/m-k and 6 W/m-k thermal conductivity.

THERM-A-GAP Pads are very soft, conformable, thermally conductive silicone and non-silicone elastomers for filling uneven gaps between a semiconductor component and a heat generating surface. THERM-A-GAP pads are available with a thermal conductivity from 1.0 W/m-K to 8.3 W/m-K, and are available in a variety of thicknesses and liner configurations to suit application needs.

Our top cell foam potting utilizes an optimized viscosity to encapsulate the tops of cylindrical cells, wire bonds, and bus bars without flowing into or filling the entire module. This safeguards the encapsulated fragile electronics from vibration, debris, and damage during assembly, use, and service.

In the event of a cell entering thermal runaway, these materials are engineered to allow an individual battery cell to vent normally while remaining in place on other cells, thereby providing the remaining cells protection from heat, chemicals, and fire. replace traditional adhesive tapes and separators allowing for more cells to be placed in the same space and reduce overall thermal impedance.

Press-in-Place seals can be used for reliable sealing of electronic component housings such as inverters, converters and control boxes, as well as for sealing small and medium-size housings or covers of batteries, fuel cells and e-axles. 

PIP seals have been developed specifically for use in narrow, tight and complex grooves. They prevent potential bi-directional micro leakage at the housing components. Special knubs on the side ensure reliable retention of the seal inside the groove and prevent the seal from dropping out of the groove after or during installation.  

Warp Seals are special static seals that compensate for axial, radial and/or angular misalignment within a wide tolerance range. They are suitable, for example, for sealing port connections and feedthroughs of all kinds in housings.

Covering a wide range of tolerances allows for easy assembly of the various components of a system without major design or functional limitations.

Benefits:

• Compensation of large axial and radial misalignment
• Compensation of angular misalignment
• High temperature resistance in case of suitable compound selection
• Excellent media resistance in case of suitable compound selection
• Easy installation
• Increased assembly safety when using integrated back-up rings

CHO-FORM® form-in-place (FIP) gaskets are ideal for densely populated electronic packaging, especially where intercompartmental isolation is required.  The form-in-place characteristics mean the CHO-FORM can be used in rapid prototyping applications on substrates such as castings, conductive plastic housings and at board level.  Ideal for automotive sensor housing and battery management systems, FIP can reduce installed cost of an EMI gasket by up to 60%.

JMC-700K Dielectric Coating
JMC 700k is a matte black heat-cure, epoxy-based coating provides excellent electrical insulation and protects against corrosion and heat. JMC-700k can be spray or dip applied to cooling plates, battery boxes or permanent magnets for e-motors.

Sipiol Ultra-Violet (UV) Cure Dielectric Coating
Sipiol UV is a UV-cured, VOC-Free, 100% solids, dielectric coating that cures in seconds that has superior adhesion to metals and plastics. It’s electrically insulative and can eliminate PET tapes and powder coating allowing you to decrease the risk of a shock-induced delamination of cells from cooling plates, replace traditional adhesive tapes and separators allowing for more cells to be placed in the same space and reduce overall thermal impedance.
