MOOC - Rubber Technologist - Basic Level
Polymer technology
This unit goes more into detail on polymer structures and in-rubber properties. The student acquires a thorough understanding of the character of the four most commonly used polymers: NR, SBR, BR and EPDM.
SBR & BR:
This element elaborates on the most commonly used synthetic polymers SBR and BR, which are related as SBR is an extended version of BR. These two polymers are commonly applied in tire treads for low rolling resistance with excellent grip.
RUBTECHB.U2.E2.PC1
The student has a basic understanding of the production methods of the polymer raw materials.
RUBTECHB.U2.E2.PC2
The student is able to draw the polymer backbone of SBR and BR and has a basic understanding of grade, their character and acronyms.
RUBTECHB.U2.E2.PC3
The student knows typical SBR/BR applications and is able to recognize how SBR styrene and BR ratio influences in-rubber character and tire tread properties (wear, grip and rolling resistance)
RUBTECHB.U2.E2.PC4
The student knows how the SBR styrene and vinyl content influence the in-rubber character (glass transition temperature) of the polymer
RUBTECHB.U2.E2.PC5
The student has a basic understanding of difference in properties of SBR, BR and NR, especially related to tire applications
