How does functional masterbatch help plastic agricultural film? By adding functional masterbatch, plastic agricultural film can achieve superior thermal insulation, UV resistance and other properties. The following is a detailed introduction for you:

1. Agricultural film anti-fogging function masterbatch

Antifog agents are mostly partial esters of fatty acids and polyols. Commonly used fatty acids are saturated or unsaturated acids of C11 to C22. Commonly used polyols are glycerol, sorbitol and their anhydrides. Generally speaking, the esters of medium-chain fatty acids have a good anti-fog effect at the initial stage, and the esters of long-chain fatty acids have a long-lasting anti-fog effect.

The content of anti-fogging agent in the masterbatch generally does not exceed 20%. Because the anti-fog agent is a surfactant compound, it has a certain degree of lubricity. When the content in the master batch reaches a certain level, it will be over-lubricated and cannot be granulated.

2. Agricultural film insulation function masterbatch

After adding heat preservation function masterbatch to agricultural film, it has little effect on film transmittance, but it can block ultraviolet rays harmful to crops during the day, and can prevent the loss of a large number of infrared rays at night, and increase the temperature in the shed. Compared with ordinary shed film, the insulation masterbatch can increase the average shed temperature by 1-2 ° C, increase the unit yield by 40% -50%, and harvest time about 10 days in advance, which has obvious economic and social benefits.

The ground temperature at night mainly radiates the heat stored during the day in the form of infrared rays, which causes the temperature in the shed to decrease. Therefore, the effective ingredient of the heat-preserving masterbatch is an infrared blocking agent.

3.Multifunctional agricultural film special function masterbatch

The functional masterbatch is added to the agricultural film, so that the agricultural film has various functions such as anti-aging, anti-fog, antistatic, heat preservation, etc., making it an ideal multifunctional masterbatch for agricultural film.

The master batch was developed on the basis of polyolefin anti-aging master batch and anti-fog agricultural film master batch. In addition to its antioxidants, light stabilizers (hindered amines), composite anti-fog agents (with initial, long-lasting, high and low temperature anti-fog and sputum properties), its formula is supplemented with insulation fillers (of SiO2) and a small amount of anti-static Agent and other additives. The carrier resin can be LDPE resin with a melt flow rate (MFR) of 2g / 10min.
