Why is ürünlerden used instead of ürünler, and what role does it play in the sentence?

Ürünlerden is the plural noun ürünler ("products") with the ablative suffix -den. In Turkish comparatives, the standard of comparison is marked with the ablative case—this functions similarly to the word "than" in English. Thus, ürünlerden means "than (the) products."

How is the comparative form constructed in the phrase daha dayanıklıdır?

The comparative is built by placing daha ("more") before the adjective and combining it with the adjective dayanıklı ("durable"). The suffix -dır is then added to form the predicate, resulting in daha dayanıklıdır, which means "is more durable."

What is the function of the suffix -dır in dayanıklıdır?

The suffix -dır functions as a copula in Turkish. It attaches to the adjective dayanıklı to form a complete statement about the subject—in effect, it works like the English verb "is," confirming that the product possesses the quality of being "more durable."
