◆Performance:
-Modified from 6PPD, 6PPD-L has significantly less odor and VOC and is much less volatile compared with 6PPD. It can effectively reduce the odor of rubber compound and final products.
-6PPD-L has the same performance with 6PPD in other aspects.

◆Application:

-6PPD-L and 6PPD have the same performance and can be applied interchangeably.

-It is recommended that 6PPD-L be applied to rubber products with higher requirements for odor and VOC, such as tires, conveyor belts, and rubber hoses.

◆Packaging:Paper/plastic packages with a net weight of 25kg per package.

◆Transportation Condition:Clear vehicle with ceiling, avoiding sunshine, rain and long-term extrusion，keeping away from hot source.
