PRC-CPPIA CONFERENCE

In the event, the Association has invited experts from both at home and abroad to address and communicate. In the conference, we will share the innovative cases of the rotomolding industry in emerging application fields; report on the progress of the formulation of various standards in the rotomolding industry; share industry opportunities and challenges under the new situation; analyze the latest industry development trends in the fields of new materials, new technologies, new equipment and new applications ; commend advanced enterprises and individuals in the industry. Furthermore, 2024 is also the 20th anniversary of the establishment of Rising Sun Rotomolding. Rising Sun will hold an open day at its new factory on 20 th April.

Seminar Topic Introduction Rotomouldable Materials – What should you know about them 

• Material Types, Polyethylene (LDPE, LLDPE, HDPE, mPE & C4, C6, C8) & Speciality grades (XLINK, PP) 

• Technical Data Sheet properties - MFI, Density, Flexural Modulus, Tensile Strength, ESCR, UV. What do they mean, how are they tested, what you are not told. 

• Plus the forgotten Anti-Oxidant additives and why they are important to materials.

• Long term design properties - HDB and Creep - why are they important for structural products, like large storage tanks or underground tanks, Finite Element Analysis. 

• Colouring plastic – dry blending and melt compounding process. 

• Powder process – production process and problems, Micropellets. Powder moulding problems. • Colour pigments - thermal stability, light stability, weatherability 

• Identifying problems caused by incorrect compounding of raw materials, and potential effect on your moulded products service life. 

• Trouble shooting product appearance problems associated with coloured powder materials 

• Colour fading – why some materials are not equal 

• Powder Quality Control - review the three quality tests - Dry Flow, Particle Size Distribution & Bulk Density - what can you do to improve consistency of your powder materials. 

• Multi-layer materials
