BS-867 | Low Pressure Molding (LPM)

Main features

Molding resin suitable for automotive applications
Good versatility for broad process and performance
Flammability UL94:V0

Product Description

BS-867 Black is a pure copolymer polyamide hot melt resin, non-reactive and solvent-free, engineered specifically for low pressure molding (LPM) applications. Optimized for both automotive and electronic environments, BS-867 combines excellent process versatility with high-performance thermal, mechanical, and electrical properties.

Its enhanced thermal resistance and UL94 V-0 flammability rating make it a preferred choice for overmolding connectors, cable assemblies, and sensitive electronic modules requiring robust environmental protection and electrical insulation.

BS 867 was developed specifically for improving adhesion on a wide range of substrates and offers cohesiveness at negative temperatures (-50°C). It is mainly used for molding electronic/electric components, connectors and cables.

Typical Applications:

Overmolding of automotive sensors, ECUs, and wire harnesses
Encapsulation of printed circuit boards (PCBs) and electrical components
Strain relief and environmental protection of connectors and terminals

Physical Properties

Viscosity

Viscosity
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application

Mechanical Properties

Hardness Hardness Hardness is a dimensionless quantity. There is no direct relationship between measurements in one scale and their equivalent in another scale or another hardness test.

Tensile Strength

Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.

Tensile Strength

Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.

Thermal Properties

Glass Transition Temperature (Tg)

Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.

Curing Conditions

Curing Schedule Curing Schedule Curing schedule is the time and temperature required for a mixed material to fully cure. While this applies to materials that cure with heat, there are also other materials that can be cured with UV. Even though some materials can cure on ambient temperatures, others will require elevated temperature conditions to properly cure. There are various curing schedules depending on the material type and application. For heat curing, the most common ones are Snap cure, Low temperature cure, Step cure and Staged cure. Recommended cure type, schedule, time and temperature can always be found on the Technical data sheets.
Cure Temperature	70 °C
Mold Temperature	20 - 60 °C
