Hsin Sou Chemical HSINSOU NYPAS

• Causing the permanent anti-static property to styrene resins
• Injected parts will still show original anti-static abilities after many times watern washing as per suitable process to compound styrene resins with HSINSOU NYPAS in proper ratio ,HSINSOU NYPAS gives the styrene resins a permanent antistatic property.
• Slightly influences to mechanical property of styrene resins.
• Superior heat stable ability ,thus less influences to styrene resins in heat applications.
• Suitable for I C relative products and other easily hurting of sensitive in static environment

1). General procedure

As shown in figure 1 .HSINSOU NYPAS and styrene resin are recommend process as following : . Pigment may be added as necessary during the dry-blending process or the neading process dry-blended using a blender , such as tumble , and are neaded and pelletized using a twin screw extruder.

Figure 1. General procedure for application of PLEASTAT NC 7530

2.Amount to be Applied

ABS : As per previous process , 20 % NYPAS to be added
HIPS : As per previous process , 15 % NYPAS to be added 

3. Kneading Conditions

1. Use a high share rate kneader ,such as a twin screw extruder.
2. Standard kneading temperature is between 160 ℃ ~ 170 ℃ , Determine the kneading temperature according to the resin applied.
3. The Highest process Temperature for each different facility are around 200 ℃~210℃ .As lower as possible while process NYPAS into extruder, recommend process in between 150 ℃ to 170 ℃.
4. Other resin undetermined need to have more confirmation.
5. Drying of HSINSOU NYPAS

4. Drying

HSINSOU NYPAS has some hygroscopic character , but is packed in bags under moisture proof conditions ; no drying is necessary when used just after unsealing . If HSINSOU NYPAS is kept open for a long time (about 72 hours) , after unsealing , drying is necessary
