Course Objective: Provide students an introduction to
elastomeric materials and processing by investigating thermoplastic and
thermoset elastomers and rubbers, carbon black reinforcements, tooling, and
processing equipment.
Laboratory Objectives: Provide students a basic
knowledge of molding thermoplastic and thermoset elastomers, including TPE,
TPU, Silanes, and natural rubbers.
Processing methods include injection molding, compression molding, and
extrusion.

Fee: $20
fee paid by the 3rd week
of the semester or the student will be dropped.
Safety: Safety glasses with side shields must be purchased
by the student and worn at all times in the lab. Failure to do so will result in the student being removed from
the lab and being dropped from the class.
The student must read, understand and follow all safety procedures at
all times. If there are any questions
about the process, operation, or safe handling of materials, the student must
talk to the instructor.

Lab
Work (Teams of 4 students)–
·
Each
student works in a team to conduct experiments with Design of Experiments
Methodology (DOE) to identify process parameters for molding of elastomeric
materials. Each student records data in
a lab notebook to record material and manufacturing information during the lab
experiments. The format of the notebook is provided at the end of the syllabus.
·
Each
student group will complete two papers identifying the results of a lab assignment
to produce parts. The format of the paper is provided at the end of this
letter.

Elastomeric
Material Paper: Due October 11, 2001
Each student will be responsible for one paper on an elastomeric material and processing. The material can be any thermoplastic or thermoset polymer with appropriate additives. The processing method can be injection molding, extrusion, or compression molding. The paper would be 4 to 6 pages typed and double spaced. It should include
· Chemistry and properties of polymer and additives
· Manufacturing methods, including equipment, molds, molding procedures
· Applications and commercial uses
· Reference work and published papers from article reviews below.
