Do Plastic Pellets have an Odor?

Paul Gage

Recently, we have received some questions regarding plastic pellets and odors from the chemicals used to produce the pellets.   There are many different types of plastic used in the world around us.   Each type uses different chemistry in order to produce the desired properties of the plastic and polymer.   The building blocks of plastics are what are known as "monomers".  These monomers are oftentimes volatile...in other words...they are able to exist in a gas phase in the air around us. When a polymer or plastic material is produced, these monomers are linked together in a chemical reaction...

Want to do something positive for the environment as you purchase your plastic pellets?   Recycled plastic pellets might be a good option for you!  In this post we will explore the pros and cons of using recycled plastic pellets for your applications. First of all, a word of a caution.  We covered this in our "safety first" blog post, but we want to be sure the all of our customers and potential customers understand the need for caution when purchasing pellets.   Plastic pellets can contain a very large variety of "additives" which will provide some sort of functionality...

Plastic Pellet Geometry

Hello again you Pellet Pundits!   This post is going to discuss one type of inconsistency that we can find when shopping for plastic pellets.   If you have purchased pellets from different sources you are probably wondering why the different types and varieties of pellets are shaped so differently?!?!   Some pellets appear to be almost perfectly round and spherical and the shape of each pellet is very consistent.   Some are shaped like a miniature flying saucer with a disc-like in appearance.   Some are shaped like miniature cylinders.  You may even run into some pellets which have two or more different shapes in the same box!   Lets...

Plastic Pellets...How Much Do I Need?

Recently, an educated customer who was making cornhole bags asked me about the bulk density of the materials we sell.   While this customer did not know that they were actually asking about "bulk density", they asked me how much one cup of pellets will weigh!   In essence, this is the same question.  When making items like cornhole bags, weighted blankets, stuffed dolls, reborn dolls, vase stuffing, and other crafty items, it is very important to consider the bulk density of the plastic pellets.   Let me explain in layman's terms. There are two "weight" properties of plastic pellets that will be important to most...

Heat Resistance of Plastic Pellets

Many of you crafters will have some questions and concerns about the heat resistance of your products...both the pellets as well as your own creation!   You are wise to consider this property BEFORE you purchase your resin pellets and materials! Most of the products which will be sold into the pellet market will be "semicrystalline" polymers.   This means that the product morphology or structure is crystalline in nature.   A good analogy is a salt crystal.   The polymers and mulecules line up and pack tightly and efficiently creating a crystalline lattice that takes energy to break up.   When this structure is heated...
