Question 1

What are the different types of rubber molding?

Accepted Answer

Compression molding, injection molding, and transfer molding.

Question 2

What is compression molding?

Accepted Answer

compression molding uses pressure and heat to mold the rubber into the shape required.

Question 3

What is transfer molding?

Accepted Answer

Rubber transfer molding uses a process similar to compression molding but has a transfer system on the top of the mold that feeds the rubber into multiple mold cavities when the press is closed.

Question 4

what is injection molding?

Accepted Answer

it is pre-heated, the rubber flows more readily into the mold, allowing for higher cure temperatures, shortening the curing cycle.

Question 5

What is Buna-N?

Accepted Answer

Nitrile (Buna-N) is a general purpose oil resistant polymer which has good solvent, oil, water and hydraulic fluid resistance, good compression set, abrasion resistance and tensile strength. Nitrile should not be used in highly polar solvents such as acetone, and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.

Question 6

What is Rubber used for in the Agriculture Industry?

Accepted Answer

The farm and agriculture industry requires rubber parts that can protect against leakage, resist chemical intrusion and seal openings from dust, contaminants and moisture. Applications are also often exposed to the elements for extended time periods, so rubber components must resist ozone, oils, and ultraviolet rays. Minor Rubber is an expert in developing specialty rubber parts for a variety of applications operating in all types of environmental conditions. With an extensive inventory of stock rubber parts, expedited delivery is available. We offer turnkey Original Equipment Manufacture services and can private label products for fabrication kits or retail sale.

Question 7

What are Grommets?

Accepted Answer

Grommets are useful in electronics applications when a wire or tube needs to pass through metal or another material that may cause damage. Most commonly, they protect cables from sharp corners and edges. We offer standard insulation grommets in Buna-N, and we also manufacture Mil-Spec grommets for military applications, vibration mount grommets to protect components from noise & vibration, and other specialty grommets. Grommets can be pushed into place using our grommet inserter tools.

Question 8

What is Natural Rubber?

Accepted Answer

Minor Rubber manufactures natural rubber parts. Natural Rubber has many good characteristics. It has high resilience, good compression set, food roll building behavior, and molding properties; very good friction surface, but not a fine smooth surface when ground; high tear strength, low crack growth; usable for ketones and alcohol, and good low temperature properties.

Question 9

What is EPR or EPDM Rubber?

Accepted Answer

Ethylene Propylene (EPR, also called EPDM) is a polymer with outstanding properties. It has exceptionally good weather aging and ozone resistance; excellent water and chemical resistance; excellent resistance to gas permeability, and excellent resistance to aging due to exposure to steam; and heat, resistance excellent up to 350°F. Ethylene Propylene is a polymer where oil and solvent resistance is poor, however, it is fairly good in ketones and alcohols. It is not recommended for food applications or exposure to aromatic hydrocarbons.

Question 10

What is SBR?

Accepted Answer

Minor Rubber manufactures SBR rubber parts.  SBR (styrene-butadiene rubber) is a low cost non-pil resistant material. It has good water resistance and resilience up to 70 durometer; compression set becomes poorer with higher durometer; generally satisfactory for most moderate chemicals and wet or dry organic acids. SBR is not recommended for ozone, strong acids, oils, greases, fats and most hydrocarbons. SBR can be molded.
