RE: DIFFERENCES IN COLOR OF ULTRA-FLOW 500 LOT 11806
Dear Sir,
This is to guarantee and assure you that the color difference of our product Ultra-Flow 500 (UF500)
will neither negatively influence the performance of the product nor the properties of the finished goods.
1. The color of UF500 is from light beige to brown.
2. The feed stock for UF500 is based on fatty acids which are prone to oxidation. Therefore,
the surface of each individual pastille would oxidize (change of color from light to darker shade)
depending on the storage condition like temperature, humidity and time.
3. The color difference of UF500 has no negative influence on the performance of the product.
Also, color difference has no negative influence on the physical properties of the finished rubber
goods.
4. All our products are tested and guaranteed by our QC department prior to shipment to customers.
I hope the above explanation is helpful to ease out your doubtfulness.
