Xylonite – Meaning, Definition, Synonyms and Antonyms
Xylonite is a noun for an early plastic made from cellulose nitrate, historically used to imitate materials like ivory and wood.
Meaning:
Xylonite refers to an early plastic (often described as an early “synthetic” material) produced from cellulose nitrate and used widely in the late 19th century through the early 20th century. You may also see it discussed in the context of celluloid-related materials, since the same general family of early plastics helped replace certain natural materials in everyday items.
Definition:
Xylonite is a durable, moldable material that was developed as a substitute for ivory, wood, and other natural materials. Because it could be shaped and finished to resemble more expensive or harder-to-source materials, it was used to manufacture combs, buttons, knife handles, and decorative objects. Over time, it fell out of favor due to safety concerns, including its flammability, as newer plastics with better heat and fire resistance became available.
Example Sentences:
- In the early 1900s, Xylonite was widely used to make buttons and combs because it was strong and easy to mold.
- The vintage Xylonite handle on the knife closely resembled ivory, which made it popular for display and everyday use.
- Xylonite helped drive the shift from natural materials toward engineered polymers during the early age of plastics.
- The decorative box was made of Xylonite, giving it a wood-like look with more flexibility in design.
- Collectors often research Xylonite items because its chemistry and safety profile differ from many modern plastics.
Xylonite Synonyms:
