1. Product analysis of PP scratch resistant agent
PP scratch resistant agent is an additive used to improve the scratch resistance of polypropylene (PP) materials.
Although polypropylene material has many advantages such as low density, good mechanical properties, and ease of processing and recycling, its surface hardness is relatively low and it is easily scratched, which affects the appearance and service life of the product.
The addition of scratch resistant agents can effectively reduce the friction coefficient of PP material surface, thereby improving its scratch resistance performance. There are currently two main types of scratch resistant agents commonly used in the market: amides and organosilicon.
Amide based scratch resistant agents, such as erucic acid amide and oleic acid amide, can migrate from the interior of the material to the surface during polymer cooling, forming a thin lubricating layer that reduces surface friction coefficient and improves scratch resistance.
However, these small molecule additives may degrade and precipitate under photothermal action, resulting in surface stickiness and affecting scratch resistance.
Organosilicon scratch resistant agents are mainly composed of polysiloxane chains, which have low surface tension and can effectively reduce the friction coefficient of PP surface.
This scratch resistant agent, due to its unique molecular structure and the characteristics of both organic polymers and inorganic compounds, can improve the scratch resistance of PP while maintaining good dispersibility and comprehensive mechanical properties.
In addition to adding scratch resistant agents, filling reinforcement and blending modification are also common methods to improve the scratch resistance of PP.
For example, adding an appropriate amount of fillers such as wollastonite or glass fiber can improve the mechanical properties of PP, thereby enhancing its scratch resistance.
In terms of blending modification, PP can be blended with components such as polyethylene (PE), polytetrafluoroethylene (PTFE), or nylon 6 (PA6) to obtain composite materials with excellent scratch resistance.
The use of scratch resistant agents is particularly important in the application of automotive interior materials. The DX85 series scratch resistant agent developed by Xiangxi New Materials Co., Ltd. utilizes organic silicon modification technology to endow automotive PP interior materials with excellent scratch resistance, low volatile organic compound (VOC) emissions, and low stress whitening performance.
This series of products emphasizes differentiation in the research and development process to meet the constantly changing needs of the market and customers.
