How to choose the right type of polyethylene injection molding compound in toy manufacturing?

Choosing the right type of polyethylene injection molding compound is crucial to the quality and safety of toys. Here are a few key factors that can help you choose the right polyethylene injection molding compound in toy manufacturing:

Toy usage environment:

Indoor or outdoor: If the toy is mainly used in outdoor environments, choose a polyethylene compound with strong ultraviolet (UV) and weather resistance.

High or low temperature: Consider the performance of the toy under extreme temperature conditions and choose a suitable thermally stable polyethylene compound.

Physical properties of toys:

Hardness and flexibility: Choose a polyethylene compound with appropriate hardness and flexibility based on the functional requirements of the toy. For example, soft toys may require higher flexibility.

Strength and impact resistance: For toys that are prone to impact or falling, choose a polyethylene compound with higher impact resistance.

Safety and non-toxicity:
Compliance with standards: Make sure the selected polyethylene compound meets international toy safety standards, such as ASTM F963, EN71, etc.
Non-toxicity: Choose a certified non-toxic, low-migration polyethylene compound to ensure that the toy is safe when it comes into contact with the skin or mouth.

Processing performance:
Flowability and moldability: Select polyethylene compounds suitable for injection molding, ensure that the material's fluidity is suitable for mold design, and reduce production defects.
Cooling speed: Consider the cooling characteristics of polyethylene compounds to optimize production efficiency and reduce production costs.

Additional functions:
Coloring and decoration: Select polyethylene compounds that are easy to color and add decoration to meet design and market needs.
Antibacterial property: For toys that require antibacterial properties, select polyethylene compounds with antibacterial additives.

How do polyethylene injection molding compounds perform in high or low temperature environments? How does this affect the use of the toy?

The behavior of polyethylene injection molding compounds in high and low temperature environments has a significant impact on the use of toys. Understanding these effects can help you choose polyethylene compounds suitable for different environmental conditions, ensuring the quality and safety of your toys. The following is the performance of polyethylene injection molding compounds under different temperature conditions and its impact on toy use:

Performance in high temperature environments
Thermal stability:
The thermal stability of polyethylene is relatively high, but in high-temperature environments, especially when the temperature exceeds its melting point (about 130-140°C), polyethylene may soften or deform.
If the toys are often exposed to high temperatures (such as toys in cars), it is necessary to choose a polyethylene compound with good thermal stability.

Physical property changes:
High temperatures may cause the strength and rigidity of the polyethylene compound to decrease, affecting the durability and structural stability of the toy.
Deformation or expansion may occur, affecting the appearance and functionality of the toy.

Surface quality:
High temperature environments may cause discoloration or degradation on the surface of the toy, affecting its appearance and safety.

Performance in low temperature environments
Low temperature brittleness:
Polyethylene becomes more brittle at low temperatures, which may reduce the material's toughness and increase the risk of breakage.
For toys used in cold climates, it is important to choose a polyethylene compound that has good impact resistance at low temperatures.

Material hardness:
Low temperatures will harden the polyethylene, which may cause the toy to feel harder, less soft and comfortable when in use.

Durability:
At low temperatures, the durability of polyethylene may be affected, especially if the toy is frequently placed in a freezing environment, which may accelerate the aging and cracking of the material.

Impact on toy use
Security:
Changes in the properties of polyethylene under extreme temperatures may affect the safety of the toy. For example, deformation may occur at high temperatures and brittleness may occur at low temperatures, which may pose risks to children's safety.

Functionality:
The functionality of the toy may be affected, for example deformation or changes in hardness may prevent the toy from functioning or operating properly.

Durability:
The durability of toys can be affected by temperature changes. Choosing a polyethylene compound with good high and low temperature stability can improve the overall durability of the toy.
