What You'll Learn
K'Nex plastic is called polyoxymethylene
K'Nex is a construction toy system created by Joel Glickman and was first introduced in America in 1992. The basic K'Nex pieces used to make models include rods, connectors, and bricks. These pieces are made out of polyoxymethylene plastic, which is a strong, flexible, and high-quality material.
Polyoxymethylene, also known as polyacetal or Delrin, is a type of plastic that is known for its hardness, toughness, and stiffness. It has excellent creep resistance and solvent resistance, only dissolving in hot solvents such as chlorophenols and benzyl alcohol above 70°C. This makes it a suitable material for K'Nex pieces, as they need to be rigid enough to stay together but also easy for children to snap and unsnap.
The K'Nex brand is particularly strong in Europe, where the company makes about two-thirds of its sales. The company is committed to manufacturing in the United States, with nearly all parts produced by K'Nex Industries Inc. in Hatfield, Pennsylvania. The K'Nex factory is located in a 125,000-square-foot facility and is proud to be family-owned and operated.
K'Nex sets provide a unique interlocking plastic rod and connector system that allows builders to create a vast array of structures and models. With the inclusion of specialized parts such as gears, wheels, and pulleys, K'Nex enables builders to design dynamic and movable structures. K'Nex is designed for people of all ages and interests, from children to adults, and helps to strengthen problem-solving, spatial awareness, and engineering skills through hands-on creation.

K'Nex plastic is four times the price of polypropylene
K'Nex is a construction toy system created by Joel Glickman and was first introduced in America in 1992. The basic K'Nex pieces used to make models include rods, connectors, and bricks, which are made out of polyoxymethylene plastic, also known as a proprietary brand of acetyl copolymer. This type of plastic is about four times the price of polypropylene, which is what most plastic toys are made of.
The reason for the higher price of K'Nex plastic is due to its specific characteristics and high quality. The pieces need to be rigid enough to stay together but also flexible and easy to snap and unsnap by children. This unique combination of properties justifies the higher price of the acetyl copolymer plastic used in K'Nex toys.
The K'Nex brand is particularly strong in Europe, where the company makes about two-thirds of its sales. The company is committed to manufacturing in the United States, with 90% of its parts and 80% of its finished products being made in Pennsylvania. This domestic production may also impact the price of K'Nex toys, as labour and production costs in the United States may be higher compared to overseas manufacturing.
Despite the higher price of the plastic, K'Nex has been a successful toy brand, offering endless creative possibilities for children and adults alike. The versatility and durability of the pieces have led to its use in educational settings, enhancing problem-solving, spatial awareness, and engineering skills. The high-quality plastic ensures that K'Nex sets can withstand repeated use and provide long-lasting play value.
In conclusion, the K'Nex plastic being four times the price of polypropylene can be attributed to the unique properties of acetyl copolymer. This specific type of plastic allows K'Nex pieces to have the rigidity and flexibility required for their construction toy system. The higher price of the plastic contributes to the overall retail price of K'Nex sets but also ensures their durability and creative potential, making them a popular choice for both children and adults.

It's strong, flexible, and has excellent creep resistance
K'Nex toys are made out of a proprietary brand of acetyl copolymer, a strong, flexible material with excellent creep resistance. This plastic is about four times the price of the polypropylene that most plastic toys are made of. However, K'Nex requires the specific characteristics of this high-quality plastic. The pieces must be rigid enough to stay together but not so rigid that children's hands have difficulty snapping and unsnapping them.
The plastic used in K'Nex is called polyoxymethylene, also known as polyacetal or Delrin. It is a hard, tough, and stiff plastic with excellent creep and solvent resistance. It is only dissolved by hot solvents such as chlorophenols and benzyl alcohol above 70°C.
Polyoxymethylene plastic has the disadvantage of crystallizing or hardening extremely quickly. If it dries out, it will form hard plastic flakes. It is processed by melting and then extruding with good temperature control. When using polyoxymethylene, it is important to have very good temperature control to avoid distortion or warping as the outside cools and crystallizes while the inside is still hot.
The excellent creep resistance of K'Nex plastic ensures that the toys can withstand prolonged exposure to stress and deformation without failing or breaking. This makes K'Nex toys durable and long-lasting, even with frequent use and assembly.
