The Importance Of Colouring Plastics
Plastics play an integral role in our daily lives and can be found in different forms and colours almost everywhere. However, do you understand the purpose and actual effect of plastic pigment colouring?
Enhance Appearance And Commodity Value
One of the main functions of plastic colouring is to beautify products and enhance the attractiveness and market competitiveness of commodities. Consumers are often first attracted by the appearance of goods, and then further understand its function and quality. Through carefully selected colours, plastic products can show individuality and fashion, catering to consumers’ unique demand for colours.
Identification And Marking Function
Colour also has a clear marking function in plastic products. For example, telephone cables are marked with specific colour spectrums, traffic signs, sanitation workers’ clothing, warning signs, etc., all of which convey information and guarantee safety through colours. In addition, the corporate logo colour also shows the brand image. Like Nike chose red, symbolising vitality and sportsmanship, which is highly compatible with its brand positioning.
Packaging Concealment And Protection
Plastic colouring can also play a protective role, especially in the packaging of food, drugs and cosmetics, not only to beautify the packaging, but also to prevent the deterioration of the contents.
Enhancement Of Light Resistance And Weather Resistance
Adding the right amount of carbon black can effectively improve the light resistance and weatherability of plastics, especially in polyolefin plastics, this way can significantly improve its anti-aging ability.
Improvement Of Material Properties
By adding special materials, plastics can gain certain unique properties. For example, the addition of carbon black improves electrical conductivity, and composite fibres made for use in garments can also act as anti-static agents.
Giving Plastics Special Functions
● Promote crop growth: the use of coloured films can selectively transmit light, regulate the surface temperature, help crop growth, with weed control, insect avoidance and other effects.
● Energy saving and environmental protection: Plastic products coloured by metal oxide pigments can reflect infrared rays and reduce surface heat transfer, thus achieving the effect of energy saving.
● Military use: some metal oxide pigments can also imitate the function of chlorophyll, which is suitable for camouflage and concealment of troops’ equipment.
Plastic coloring is not just a simple colour treatment, it has an unnegligible role in the optimization of product performance and the realization of special functions.
