Description   Molding compounds and resins are industrial plastics and polymers that are suitable for forming. They are used in injection molding, compression molding, reaction injection molding (RIM), resin transfer molding (RTM), and blow molding. Types include thermoset resins, gel elastomers, encapsulants, potting compounds, composites, and optical grade materials. Typically, products are supplied as pellets, liquids, and powders.   Types   The GlobalSpec SpecSearch...

Q:
What new technologies are influencing molding compound and resin design?
8 answers
Answers:
Increasing usage of composites in aircraft engines is requiring higher temperature performing resins in every type of composites; molding compounds as well. And their usage in more load critical parts, but also cost critical parts requires resin systems which are easy to use in manufacture.

Q:
From your perspective, which companies are creating the most innovative molding compounds and resins?
9 answers
Answers:
Ten Cate has a wide range of thermoset compounds finding wide usage. Hexcel, although a major player and setting the example with the window frame on B787, is too secretive to my opinion. Raptor Resins working on BMI resins also used in compounds is on the right track for high performance, high temp., affordable resins.

Q:
Please share with us any “non-standard” applications that molding compounds and resins have been used for.
6 answers
Answers:
More likely to be found outside our main focus "Aerospace" in the "machines" industry. High modulus, stiff compounds are used in various parts to improve performance (speed) of robots.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of molding compounds and resins?
4 answers
Answers:
Yes, in the sense of losing a lot of money in the injection procedure of parts using a resin with very high viscosity, when low viscosity was a requirement for the injection of that part. Fiber reinforcement and preparation time were lost.
~Antonio O, Research & Development, El Puerto de Santa Maria, Spain
Given that a design brief usually includes a cost target, I'm sure every designer would prefer to use a 'better' material. - I guess we have all made mistakes.

Q:
What would your design or feature "wish list" be for this product?
10 answers
Answers:
Due to the nature of our business each product and material we select are for different needs. I would like to know more about what other materials manufacturers are researching and producing that I could offer for use in artistic and creative projects.
~Technical Support/Services, Bristol, United Kingdom
Most important for us is consistent quality, so top of the wish list from my point of view is easily moldable (good flow resins) and controlled fibre orientation in each part.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using molding compounds and resins?
4 answers
Answers:
Ensure that your supplier is running a well-managed quality assurance program with records of the material lots and that they are ready and able to share that information as needed.
~Robert P, Design Engineer, Ferndale, WA
Keep it simple - if you need to use the very special grades, think again.
~Neil G, Research & Development, Brighouse, UK
Yes, regarding the application they should select their resin.
~Antonio O, Research & Development, El Puerto de Santa Maria, Spain
Adhere to your required spec

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of molding compounds and resins?
4 answers
Answers:
Look at the technical information of the resin; understand each parameter and realize if that resins suits with their application.
~Antonio O, Research & Development, El Puerto de Santa Maria, Spain
Treat each component as independent - don't just use 'the same as last time'.
~Neil G, Research & Development, Brighouse, UK
Stick to the brand and spec customer suggests & even the place of purchase.
