introduction of DINP
DINP (Diisononyl Phthalate) is a plasticizer commonly used in PVC (Polyvinyl Chloride).
Chemical Properties
Molecular formula: C₂₆H₄₄O₄
Molecular weight: 418.61
Appearance: Transparent oily liquid with a slight odor
Density: Approximately 0.98 g/cm³
Melting point: -48°C
Flash point: 235°C
Action Principle
PVC itself is a rigid plastic. By adding DINP, it can insert between PVC molecular chains, weakening the forces between PVC molecular chains. This allows the chains to move relative to each other more easily, endowing PVC products with softness, flexibility, and elasticity.
dINP advantage
Excellent Compatibility
It has good compatibility with PVC. Even when used in large quantities, it is not prone to precipitation, ensuring the long-term stability of product performance.
01
Superior Weather Resistance
It exhibits excellent resistance to light, heat, and aging, enabling PVC products to maintain good physical properties under different environmental conditions and extending their service life.
02
Superb Insulation
It imparts good electrical insulation properties to PVC products, making them suitable for applications requiring insulation, such as wires and cables.
03
Relatively Environmentally Friendly
Compared to some traditional plasticizers like DOP (Dioctyl Phthalate), DINP is generally considered more environmentally friendly with lower toxicity, and it is widely used in PVC products with high safety requirements, such as toys.
04
Good Processing Performance
Under typical extrusion processing conditions, DINP can reduce the melt viscosity of the mixture more effectively than DOP, helping to lower die pressure, reduce mechanical wear, or improve extrusion productivity.
05
Low toxicity
It is interpreted that the product is non-toxic to environment and thus has no health risks for the community in general. Furthermore, it is a plus for the product to be used in consumer products.
Flexibility and durability
The improvement of their mechanical properties can be obtained by means of adding them to plastics, for instance PVC, thus making them more wear- and tear-resistant.
Extreme temperatures
Besides, it can also be used in products that are stored for long periods of time.
