Dosage: It can work with polyester plasticizer to lower the migration of polyester plasticizer, or work with metal heat stabilizer, . Its compatibility is similar to DOP and its politicizing effect is better than DOP, thus it can improve quality and lower the cost. For soft products, the dosage is 5 to 10 portion. In special condition, the dosage is 10 to 30 portion. It can be used as substitute of plasticizer, stabilizer and lube partly.
Packing: Net wt 200 kg in metal pail.
