Halogen Free 　Road Map

一． Halogen Free Definition:


Currently, customers’ request of Halogen Free mainly


focuses on:


According to IEC 61249-2-21(2003)
standard in


homogeneous materials (plastic parts):


Total Cl <900ppm;


Total Br <900ppm;


Total( Cl+Br) <1500ppm;



二．Major
customers' request:

Limit flame retardant contains Br and PVC
material step by step 。

Normally, be required to conform. Halogen

三．
Wieson Halogen Free plan: (Finished parts)

1)
Collect Information : (Before May 2007) Halogen Free content

2)
Sample of Halogen free material :(From May to the end of 2007)


Have checked suppliers plastic material:


A: Non-high temperature plastic material : Halogen free PBT (sampled)


B: High temperature material:

# Halogen free Nylon HTN
series (sampled)

# Halogen free LCP series
(Halogen free material in origin)


C: Cable: Part of cables can transfer to Halogen free CABLE(TPU)

四．
Wieson Halogen Free Plan : (Implementing in 2008)

1)
Sample analysis (To be finished in Q2 　2008):

colorant 　investigation
contained


B: Confirm of production process : equipment (mold) and process risk analysis

2)
Sampling : sampling and recording (To be finished in Q2 　2008)

4)
Cost evaluation: evaluate customer’s sample price (To be finished in Q2　 2008)

5)
Sample test and customer confirmation (To be finished in Q3　 2008):
