High Plasticizing Efficiency Plasticizer DBP/Dibp for Artificial Leather and Printing Inks

Product Description

Product Description

Plasticisers are important functional additives in the processing of PVC and other polymeric materials, primarily used to improve the material's flexibility, elongation, low-temperature resistance and processability. Our company supplies two commonly used types of plasticisers: DOP (Dioctyl Phthalate) and DOTP (Dioctyl Terephthalate). We can assist customers in selecting the appropriate product based on their specific requirements regarding flexibility, processability, weather resistance and intended application. Through the integration of resources across multiple factories and supply chain management, we are able to provide a stable supply, batch-by-batch quality control and technical documentation such as COAs, TDSs and MSDSs, meeting the production requirements for PVC flexible products, PVC cable compounds, flexible films, flooring, synthetic leather, pipes and other plastic products.

Suitable Manufacturing Processes

DOP and DOTP are primarily used in the production and processing of PVC flexible products and plasticised PVC materials, and can be employed in processes such as calendering, extrusion, injection moulding, coating, dip coating, blow moulding and compounding and pelletising. In the production of PVC flexible films, PVC flooring, hoses, cable compounds and synthetic leather, plasticisers can be used in conjunction with PVC resin and additives such as stabilisers, fillers and lubricants to improve the material's flexibility and processability. Depending on the specific production process and the required hardness of the final product, our company can assist customers in selecting DOP, DOTP or a DOP/DOTP blend, and provide the relevant technical parameters in accordance with formulation requirements. 

Application

PVC Wires and Cables

PVC flooring and building materials

DOTP provides good flexibility, plasticizing efficiency and long-term performance, making it suitable for flexible PVC electrical and cable applications where stable processing, electrical insulation and durability are important.
Main applications:
PVC cable insulation
Cable sheaths
Flexible wires
Electrical cords

DOTP provides good flexibility, durability and overall processing performance, making it suitable for PVC flooring and flexible building materials requiring stable performance and long-term use.
Main applications:
PVC flooring
Vinyl flooring
LVT flooring
PVC floor sheets
Flexible building materials

PVC flexible products

PVC artificial leather and coatings

PVC paste resins and dip-coated products

DOP offers excellent plasticizing efficiency, flexibility and cost-effectiveness, making it a widely used choice for conventional flexible PVC products requiring good softness and easy processing.
Main applications:
PVC hoses
PVC soft films
PVC sheets
PVC sealing strips
Flexible PVC profiles
PVC mats

Both DOP and DOTP can provide the flexibility and softness required for PVC artificial leather and coated materials. DOP is commonly selected for conventional applications and cost efficiency, while DOTP is more suitable for products requiring improved overall performance and durability.
Main applications:
PVC artificial leather
Synthetic leather
Shoe materials
Furniture upholstery
Luggage and bag materials
PVC coated fabrics

DOP and DOTP can both be used as plasticizers in PVC plastisol formulations, helping control product softness, viscosity and final hardness. The appropriate plasticizer can be selected according to the production process and final application requirements.
Main applications:
PVC plastisol products
Coated fabrics
Artificial leather
PVC flooring
Dip-molded products
Flexible PVC coatings

Hot Topics Q&A

1. Do plasticisers need to be used in conjunction with stabilisers?
Yes. Plasticisers are primarily responsible for improving the flexibility of PVC, whilst stabilisers are mainly used to enhance the thermal stability of PVC during processing. As they serve different functions, they are usually required to be used together depending on the PVC formulation.
2. Why is the flexibility of PVC products inconsistent?
This may be due to batch-to-batch variations in plasticisers, weighing errors, uneven mixing, inconsistent plastification, or changes in the ratio of PVC resin to fillers. Please contact us immediately so that we can provide you with DOP and DOTP from consistent batches, along with relevant technical documentation. We will also assist you in selecting the appropriate products based on your PVC formulation, production process and target hardness, thereby helping to optimise formulation stability.
3. Why does plasticiser separation occur during production?
Common causes include excessive plasticiser addition, insufficient compatibility between the PVC resin and the plasticiser, an unbalanced formulation system, inadequate mixing and plasticisation, or inappropriate processing temperatures. We recommend a comprehensive analysis taking into account the resin grade, plasticiser dosage and processing conditions.
