CHOPPED STRANDS
K405 Chopped Strands
K405 is a versatile chopped strand that was originally designed for polyester moulding
compounds. The product has also been used successfully in epoxy moulding compounds as well
as with dry blending in phenolic applications. K405 chopped strands are used in a broad
range of applications including electrical, transportation and food grade moulding
compounds.
Features
- Excellent Pigmentability
- Low Fuzz
- Excellent Laminate Properties
- Product Consistency
- Works in Compression or Injection Moulding
- Excellent Electrical Properties
Benefits
Excellent Pigmentability. K405 chopped strands are easily pigmented, allowing the
moulder to use a wide range of colours.
 Low Fuzz
K405 chopped
strands possess low fuzz or fly, minimizing clumping.
Exceptional Laminate Properties
The K405 product has excellent laminate properties, meeting a wide range of customers'
laminate requirements.
Product Consistency
K405 chopped strands are highly consistent, providing uniform product to the customer.
The versatility of the K405 product makes it suitable for compression or injection
moulding, allowing the customer to use one product.
Excellent Electrical Properties
K405 possesses exceptional electrical properties and is used in a variety of
U.L.
applications.
Product Data
K405 is available in 3, 6, 12,5 and 18 mm lengths as standard and has a "K"
13,7 micron fibre diameter.
Processes
The K405 product is recommended for moulding compounds using 5% to 30% glass content and
in friction compounds using 5% to 15% glass content. In bulk moulding compounds it is
recommended to add the chopped strands last and use only sufficient mixing time to wet the
fibre bundles. Overmixing will shorten fibre length and reduce properties.
A plough or sigma blade type mixer is recommended. In dry phenolic mixing the glass
fibres are typically added last and mixed for a minimal time until uniform. Overmixing
will result in fuzz clumping which will reduce properties and create non-uniformities in
the mix. A plough blade type mixer is recommended.
Packaging
K405 is supplied in 25 kg heavy duty Polythene bags for the 3 and 6mm, and 20 kg for
the 12,5 and 18mm.
Approval
K405 is manufactured and tested in accordance with the Quality Management System of
Owens Corning South Africa which conforms to the requirements of SABS ISO 9002.
Storage
It is recommended that fibreglass is kept at a temperature not exceeding 25'C and a
relative humidity not exceeding 65%.
