Introduction

ABS, or Acrylonitrile Butadiene Styrene, is a common thermoplastic polymer known for its toughness, impact resistance, and heat resistance. Two common variations of ABS are Elasticized ABS and Plasticized ABS. While both materials share some similarities, they also have distinct attributes that make them suitable for different applications. In this article, we will compare the properties of Elasticized ABS and Plasticized ABS to help you understand the differences between the two.

Composition

Elasticized ABS is a modified form of ABS that contains elastomers, which are rubber-like materials, blended into the polymer matrix. These elastomers improve the flexibility and impact resistance of the material, making it more suitable for applications where flexibility is required. On the other hand, Plasticized ABS contains plasticizers, which are additives that increase the material's flexibility and reduce its hardness. Plasticized ABS is often used in applications where a softer, more pliable material is needed.

Mechanical Properties

When it comes to mechanical properties, Elasticized ABS has higher impact resistance and flexibility compared to traditional ABS. The elastomers in Elasticized ABS allow the material to bend and stretch without breaking, making it ideal for applications that require a high degree of flexibility. Plasticized ABS, on the other hand, is softer and more pliable than Elasticized ABS, but it may not have the same level of impact resistance. This makes Plasticized ABS better suited for applications where flexibility is more important than impact resistance.

Chemical Resistance

Both Elasticized ABS and Plasticized ABS offer good chemical resistance, but Elasticized ABS tends to have better resistance to certain chemicals due to the presence of elastomers. The elastomers in Elasticized ABS can provide a barrier against certain chemicals that may degrade the polymer matrix. Plasticized ABS, on the other hand, may be more susceptible to chemical attack due to the presence of plasticizers, which can leach out of the material when exposed to certain chemicals.

Temperature Resistance

When it comes to temperature resistance, both Elasticized ABS and Plasticized ABS have similar properties. Both materials can withstand moderate temperatures without deforming or losing their mechanical properties. However, Elasticized ABS may have a slight edge in terms of heat resistance due to the presence of elastomers, which can help dissipate heat more effectively. Plasticized ABS, on the other hand, may soften at slightly lower temperatures due to the presence of plasticizers.

Applications

Elasticized ABS is commonly used in applications where flexibility and impact resistance are crucial, such as in automotive parts, sporting goods, and protective gear. The ability of Elasticized ABS to bend and stretch without breaking makes it ideal for these types of applications. Plasticized ABS, on the other hand, is often used in applications where a softer, more pliable material is needed, such as in medical devices, toys, and packaging materials. The flexibility and softness of Plasticized ABS make it suitable for these types of applications.

Conclusion

In conclusion, Elasticized ABS and Plasticized ABS are two variations of ABS that offer unique properties and characteristics. Elasticized ABS is known for its high impact resistance and flexibility, making it ideal for applications where these properties are important. Plasticized ABS, on the other hand, is softer and more pliable, making it suitable for applications where flexibility is more crucial than impact resistance. Understanding the differences between Elasticized ABS and Plasticized ABS can help you choose the right material for your specific application.
