General Plastics & Composites LP
What is a composite?
Composites are simply two dissimilar materials put together to accomplish something that neither could have done by themselves.

A comprehensive glossary of industry terms is located located here.

What temperatures and pressures will composites perform well under?
Composites are easily drillable, PDC friendly, non-conductive, non-magnetic and perform in environments up to 450 F and 30,000 PSI. Materials can be matched for specific downhole environments.

What kind of composite materials does General Plastics & Composites use?
The most common types of composites are a result of combining reinforcing fibers with resin. Fibers can be a variety of items such as glass, Kevlar, carbon fiber, quartz, basalt or boron.

General Plastics and Composites utilizes many different resin systems and cloth/roving combinations to meet each component or assemblies' mechanical loading and environmental requirements.

What is the difference between thermoset and thermoplastic?
Thermoset plastic is a polymer that irreversibly cures and cannot be reprocessed. A thermoplastic is a polymer that can be re-molded and re-processed.

What is the tooling required?
Typically, precision ground shaped mandrel or diamond tooling is used to machine specific features.

Can I make a composite part out of a metal drawing?
The design will most likely change, and is dependent on component geometry and mechanical strength requirements.

What's the strength of the material?
Material strength depends on the manufacturing method, and reinforcement cloth weave/roving size and direction.

What's the best way to work with General Plastics & Composites?
Our engineers and technicians work jointly with customers to develop prototypes, choose the best composite materials and manufacturing methods for construction, and coordinate and conduct in-house testing, assuring an innovative solution for your needs.

It is best to involve our engineers early in the design phase for their expert guidance in using composite material for mechanical applications. Vital recommendations on the front-end will prevent time-consuming and costly changes at the back-end. They are experienced professionals with downhole tool design and composite materials engineering backgrounds, and are an excellent resource on customer projects.

How can I be sure that proprietary information will be kept confidential?
General Plastics & Composites maintains strict confidentiality in all interactions with our customers or would-be customers. No analytical data, reports, opinions, discussions and other information are released to any third party without your permission.

Confidentiality is a very important aspect of our work at General Plastics & Composites, and our excellent reputation in the industry is a result of not only our product knowledge expertise and service, but also for our high code of ethics.

Will General Plastics & Composites sign confidentiality agreements with customers?
Yes, confidentiality agreements will be signed upon request to our management.

What's the cost of composite materials compared to other materials?
It depends on the geometry. Typically, it is slightly more expensive, but costs can be controlled by using proper tooling.

Why are composite materials desirable for the oilfield industry?
The design requirements for drillable composites or logging tools exceed those for most other uses of fiberglass materials. This is due to the conditions these materials will be forced to undergo. These conditions include:

  • High Pressures
  • High Temperatures
  • Compatible with moisture
  • Compatible with drilling fluids
  • Compatible with cement
  • Compatible with most down hole chemicals

Since 1967, General Plastics & Composites has been providing composite materials to the oil patch, so we understand the unique conditions, and the design considerations, use of materials, performance, and required delivery and turn around time requirements for the energy industry.
