PMplast TPA 198 NC

The product

PMplast TPA 198 NC is an amber low pressure moulding resin, based on established highly functional, co-polyamide chemistry. It is designed for hot melt applications.
PMplast TPA 198 NC meets the latest requirements of electronics, e.g. protection against water, dust and chemicals.

PMplast TPA 198 NC is lead-free and has no silicone or PAH in its recipe. It fulfils the RoHS directive.
The hot melt features superior performance in ther-mal and dielectric properties which are maintained when subjected to environmental stress.

Main Properties
  • Medium viscous melt behavior
  • Listed in UL 94 V0
  • excellent adhesion to most surfaces
  • good flexibility at low temperatures
  • no curing needed
  • RoHS compliant
Resistance to Harsh Conditions

Electronic components, covered with PMplast TPA 198 NC, provide maximum resistance against conta-minants such as dust and many chemicals. It with-stands corrosive gas atmosphere, weak acids, fuels, oils, glycols and many other fluids used in automo-tive and shipping industry.

The coverage retains excellent adhesion, but remains flexible to withstand distortion of the part.

Processing

PMplast TPA 198 NC is optimized for mass production with automatic and semi-automatic applications. It can be used with tank melting and extrusion equipment. It is ready to use, if original closed bags were used. Are there opened bags, a drying step should be included (minimum 4h at 60°C) to reduce adsorbed water content. It is recommended to weld bags again after use.

In order to achieve satisfactory wetting and fault-free adhesion with PMplast TPA 198 NC, it is important to ensure compatibility with all parts of the used pro-ducts. Also the design of the mould is highly import-ant.
A cleaning process can optimize adhesion (e.g. plasma treatment or conventional washing of the parts).
