ABS VH0800D is a flame-retardant variant of general-purpose ABS, specially formulated to meet the requirements of electrical and electronics applications. This grade is known for its self-extinguishing properties, making it safer for use in environments where fire safety is a concern. VH0800D maintains an excellent balance of mechanical properties and processability, suitable for products requiring high precision and safety standards.
 
Key Features
Flame Retardant: Equipped with self-extinguishing properties to enhance safety in electrical and electronics applications.
High Mechanical Strength: Offers a good balance of toughness and rigidity.
Low Mold Shrinkage: Exhibits mold shrinkage of around 0.4% -0.6%, minimizing dimensional variability during cooling.
 
Applications
TV Monitors: Ideal for parts that require both aesthetic appeal and flame retardancy.
Wiring Devices: Suitable for components that must adhere to strict safety and durability standards.
 
Processing Guidelines
Drying: Drying prior to processing is crucial. Recommended conditions are 2 hours at 180°-190°F (82° - 88°C) or 4 hours at 160° - 170°F (71°-77°C) in a desiccant dehumidifying hopper dryer to achieve a moisture content of 0.1%. An inlet air dew point of 20°F (-29°C) or below is optimal.
