New PP material

Basell's new multi-purpose Oxy-PP material is a polar functional PP resin capable of producing oxygen components as flame retardant dispersants and coupling agents/affinity agents in engineering thermoplastic blends and reinforced polyolefins. design. Bottles made with Metocene X50182 mPP by repeated heating and blowing method can achieve the transparency of PET bottles (haze of 1.5%), and the gloss is higher than that of conventional PP.
To produce oxyPP, basell uses the same proprietary technology used to make high melt strength resins, and the company currently plans to produce oxyPPs with different MFR ranges and functional levels.
The initial emphasis was on flame retardant materials. oxyPP is said to reduce halogen and non-halogen FRs with its dispersant but does not affect flame retardancy. OxyPP is blended with a brominated FR compound and injection molded into a household plastic part such as a television cover, achieving UL 94 equivalent flame retardance, while halogen flame retardance is less than half the original value.
An order product of OxyPP showed very high MFR, 30% higher strength than non-halogen FR-PP composites, and better surface appearance.
Basell states that oxyPP resins and their ionic polymers can work together with engineering thermoplastics to create an affinity alloy effect. For example, the combination of 25 to 75 oxyPP and nylon 6 resulted in a mixture of similar positive PP and nylon: 10% to 25% increase in tensile strength and flexibility, and a 4-fold increase in MFR and color stability.
The use of OxyPP as a coupling agent can be seen in the experiment of polypropylene containing 30% glass fiber: The addition of 10% oxyPP can effectively increase the glass fiber bottle exit rate, and can greatly improve the flexural modulus, tensile strength, bending Strength, impact resistance and heat distortion temperature. OxyPP can also achieve good results in glass fiber-containing PP materials.
