Product Description

1. Brief Introduction
Synthetic resins as raw materials of plastic products are the essential materials in producing daily
supplies. Even it is different depending on the kind of synthetic resin, there are some resins
absorbing the humidity in the air at room temperature while others do not absorb the humidity.
Nylon, PET, TPU, ABS, PS and Acetal belong to the humidity absorbing resins.
Even though it is a non humidity absorbing resin, it contacts with water during production process
to cool down the melted resin. In this process, the products may contain the water. In case pigments,
inorganic fillers or antifogging agents which are hydrophilic are added, it is difficult to control water
containing phenomenon.
Synthetic resin as organic compound will cause quality problems due to the generation of bubble
because moisture is evaporated by heat during a production process even its volume is quite small.
Super Dehumidifying Masterbatch (SDM) developed by Samjin Polytech will be helpful in improving
the quality problem related to the humidity contained in the products. The recommended dosage is
1~3% depending on the content of humidity.

2. Cases of Faults caused by humidity
• Generation of surface coarsening phenomenon due to the generation of bubble
• Degrade in physical properties due to the generation of bubble (Elongation, Tensile Strength, etc.)
• Fracture when product formed in case of film (Punk occured)
• Yellowish phenomenon due to the oxidation of resin
• Gell formation due to the generation of radical

3. Advantages & Features of SDM
• Excellent humidity removing effect with a small quantity of SDM
• The existing dehulidifying agents have a limit in using due to the down grade of product trnasparency
while SDM does not affect on the transparency of the product.
• There is no change in colors even SDM is used in color products.
• No dust in SDM for a specific cutting process
